TELA-INDEX-1 Specification

Complete technical specification for TELA-INDEX-1 smart contracts - the manifest standard that ties TELA applications together.

📋

What is TELA-INDEX-1? A smart contract that serves as the entrypoint for TELA applications. It references all DOC contracts (files) and provides updateable metadata for your application.

Overview

TELA-INDEX-1 contracts serve as the "package.json" or "manifest" for TELA applications. Users enter a single INDEX SCID to access the entire application.

Key Characteristics

Property	Value
Mutability	✏️ Updateable (if deployed with ringsize 2)
Purpose	Application manifest and entrypoint
References	Lists all DOC contract SCIDs
Versioning	Built-in commit system tracks updates
Max Size	Variable (see size limits below)
MOD Support	Can integrate TELA-MOD-1 extensions

Size Limitations

📏

Critical Size Constraints

INDEX size directly impacts updateability and capacity.

Size Limits (from source code)

Limit	Size	Purpose
Maximum Installation	11.64 KB	MAX_INDEX_INSTALL_SIZE
Recommended for Updates	9 KB	Ensures room for future updates
Maximum Practical	~11 KB	Absolute deployment limit

Capacity Estimates

INDEX Size	DOC Capacity	Updateable?
< 9 KB	~90 DOCs	✅ Yes (room for growth)
9-11 KB	~100-120 DOCs	⚠️ Limited update capacity
> 11.64 KB	N/A	❌ Cannot deploy

Testing Results (from source):

~90 DOCs: Reliable updates, can add more later
~120 DOCs: Maximum capacity, may not accept additional DOCs in updates

Size Management: Use DocShards and Libraries to include more content without bloating INDEX size. Each SCID reference is ~64 bytes.

Smart Contract Functions

InitializePrivate()

Purpose: Initialize contract on deployment

Called: Once, automatically at deployment

Actions:

Stores application metadata
Stores all DOC references
Initializes version tracking
Sets up MOD integration (if specified)

Cannot be modified after deployment (immutable initialization)

UpdateCode(mods String, code String)

Purpose: Update INDEX contract with new configuration

Parameters:

mods (String) - MOD tags to enable/disable
code (String) - New smart contract code

Access: Contract owner only

Actions:

Increments commit counter
Stores update TXID
Updates hash to current TXID
Deploys new contract code

Version Tracking:

// Before update (commit 0):
STORE("commit", 0)
STORE(0, "abc123...")  // Initial TXID
STORE("hash", "abc123...")
 
// After first update (commit 1):
STORE("commit", 1)
STORE(0, "abc123...")  // Still there (history)
STORE(1, "def456...")  // First update TXID
STORE("hash", "def456...")  // Updated
 
// After second update (commit 2):
STORE("commit", 2)
STORE(0, "abc123...")  // History preserved
STORE(1, "def456...")  // History preserved
STORE(2, "ghi789...")  // Second update TXID
STORE("hash", "ghi789...")  // Updated

📜

Complete History: Every update is preserved on the blockchain. Users can access any historical version using commit TXIDs.

Rate(r Uint64)

Purpose: Rate the INDEX contract quality

Parameters:

r (Uint64) - Rating value (0-99)

Access: Public - any wallet can rate

Effect:

Stores rating from calling wallet
One rating per wallet per contract
Updates overall rating statistics

Updateability & Immutability

Update Rules

Deployment Type	Ringsize	Updateable?
Public Deployment	2	✅ Yes - owner can update
Anonymous Deployment	> 2	❌ No - permanently immutable

🔒

Critical: Once deployed with ringsize > 2, the INDEX is permanently immutable. Choose wisely during deployment!

What Can Be Updated

Via UpdateCode:

✅ DOC references (add/remove/change DOCs)
✅ Application metadata (name, description, icon)
✅ MOD configuration (add/remove MODs)
✅ dURL identifier
❌ Contract SCID (this never changes)
❌ Contract owner (without Transfer Ownership MOD)

Via SetVar (with MOD):

✅ Dynamic variables (var_*)
✅ Custom metadata (var_meta_*)
✅ Owner notes (var_owners_note)
❌ Does NOT create new commit version

UpdateCode vs SetVar

Operation	Creates Commit?	Use Case
UpdateCode	✅ Yes	Code changes, DOC updates, major versions
SetVar	❌ No	Dynamic data, metadata updates, minor tweaks

Example:

# Major update - adds to version history
» update-index your-scid
# Creates commit 1, 2, 3...
 
# Minor update - doesn't create version
» set-var your-scid
Enter key » var_owners_note
Enter value » App is temporarily offline for maintenance
# Doesn't create new commit

TELA-MOD-1 Integration

INDEX contracts can integrate TELA-MOD-1 modules for extended functionality.

MODs Field

34 STORE("mods", "vsoo,txdwd,txto")

Format: Comma-separated MOD tags

Available MODs:

Variable Store: vsoo, vsooim, vspubsu, vspubow, vspubim
Transfers: txdwd, txdwa, txto

MODs at Deployment

» install-index
# ... standard prompts ...
Enter INDEX mods (comma separated tags, or leave blank) » vsoo,txdwd

MODs in Updates

» update-index your-scid
# ... update prompts ...
Add SC TELA-MODs (y/n) » y
Enter MODs to add » txto
Enter MODs to remove »

Version Control System

Built-in Commit Tracking

TELA-INDEX-1 automatically tracks all updates:

// Initialization (commit 0)
STORE("commit", 0)          // Version counter
STORE(0, HEX(TXID()))      // Initial TXID
STORE("hash", HEX(TXID())) // Current hash
 
// First update (commit 1)
STORE("commit", 1)
STORE(1, HEX(TXID()))      // Update TXID
STORE("hash", HEX(TXID())) // Updated hash
 
// Second update (commit 2)
STORE("commit", 2)
STORE(2, HEX(TXID()))
STORE("hash", HEX(TXID()))

Accessing Version History

# View all versions
» search scid vars your-index-scid
 
# Output shows:
# commit: 3           ← 3 updates made
# 0: abc123...        ← Initial deployment
# 1: def456...        ← First update
# 2: ghi789...        ← Second update
# 3: jkl012...        ← Third update (latest)
# hash: jkl012...     ← Current version

Clone Specific Version

# Clone latest version
» clone your-index-scid
 
# Clone specific commit
» clone your-index-scid@def456...  # First update
» clone your-index-scid@abc123...  # Original version

Serve Version Control

# Serve latest (default)
» updates true
» serve your-index-scid
 
# Serve original only
» updates false
» serve your-index-scid  # Always serves commit 0

DOC References

DOC1 (Entrypoint)

Special Requirement: DOC1 must be a valid TELA-DOC-1 SCID

40 STORE("DOC1", "valid-doc-scid-here")

Purpose:

Primary file loaded when INDEX is accessed
Usually index.html for web apps
Must exist and be valid for INDEX to work

Validation:

Cannot be empty
Must be 64-character hex SCID
Must reference valid TELA-DOC-1 contract

🚨

CRITICAL: Your entrypoint file MUST be named index.html

TELA browsers (including Hologram) look for index.html as the default entry point. If your DOC1 file is named something else (like myapp.html, main.html, or Snake_Deluxe.html), your app will NOT render correctly - users will see a file listing instead of your application.

Common Mistake:

❌ DOC1: myapp.html      → Shows file listing, app doesn't load
❌ DOC1: Snake_Deluxe.html → Shows file listing, app doesn't load
✅ DOC1: index.html      → App loads correctly!

Solution: Always name your main HTML file index.html before deploying as DOC1.

Additional DOCs (DOC2, DOC3, etc.)

Format:

41 STORE("DOC2", "second-doc-scid")
42 STORE("DOC3", "third-doc-scid")
43 STORE("DOC4", "fourth-doc-scid")
// Continue incrementing as needed

Rules:

Sequential numbering (DOC1, DOC2, DOC3...)
All DOC stores must have valid SCID values
Empty/invalid DOC stores will cause validation failure
Can include regular DOCs, libraries, and DocShards

Maximum DOCs

Practical Limits:

~90 DOCs   - Safe limit for updateable INDEX
~120 DOCs  - Maximum tested capacity
~unlimited - Theoretically, limited only by 11.64KB INDEX size

Each DOC SCID adds:

~64 bytes for the SCID itself
~10-20 bytes for STORE structure
~80 bytes total per DOC reference

Calculation:

11,640 bytes (max INDEX size)
- 1,000 bytes (base contract + headers)
- 10,640 bytes available for DOCs
÷ 80 bytes per DOC
≈ 133 DOCs theoretical maximum

Reality: ~120 DOCs due to contract overhead

dURL Conventions

The INDEX dURL identifies your application:

📖

Deep Dive: dURLs are human-friendly labels, not unique identifiers. Multiple contracts can share the same dURL. For a complete explanation of how dURL resolution works and what to do when things go wrong, see Understanding dURLs.

Standard Applications

myapp.tela              # Standard application
blog.tela               # Blog application
explorer.tela           # Block explorer
game.tela               # Game application

Special Suffixes

Suffix	Purpose	Example
`.lib`	Library INDEX	`mylib.tela.lib`
`.shards`	DocShard reconstruction	`largefile.tela.shards`

dURL Best Practices

✅ Descriptive and memorable
✅ Lowercase preferred
✅ Use hyphens for spaces (my-app.tela)
✅ Unique within your application ecosystem
❌ Don't use special characters
❌ Don't use spaces
❌ Don't exceed reasonable length (keep under 32 chars)

Rating Integration

INDEX contracts include built-in rating functionality:

Function Rate(r Uint64) Uint64
10 DIM addr as String
20 LET addr = ADDRESS_STRING(SIGNER())
30 STORE(addr, r)
40 RETURN 0
End Function

Rating via TELA-CLI

» rate your-index-scid
Enter rating (0-99) » 85
Rating is: 85  Very good (Benevolent)
Confirm rating (y/n) » y

Best Practices

Deployment Strategy

1. Plan Your Structure:

INDEX (myapp.tela)
├── DOC1: index.html (entrypoint) ← Always first
├── DOC2: style.css
├── DOC3: app.js
├── DOC4: utils.tela.lib (shared library)
└── DOC5: assets/logo.png

2. Deploy DOCs First:

» install-doc index.html  # → SCID: aaa...
» install-doc style.css   # → SCID: bbb...
» install-doc app.js      # → SCID: ccc...
# Note all SCIDs!

3. Create INDEX Last:

» install-index
# Reference all DOC SCIDs in order
# DOC1 must be your entrypoint

Update Strategy

When to Update:

✅ Adding new files (new DOC)
✅ Replacing old files (point to new DOC SCID)
✅ Removing unused files (reduce DOC count)
✅ Adding/removing MODs
✅ Updating metadata

When to Deploy New INDEX:

✅ Complete redesign
✅ Forking/cloning app
✅ Creating alternative version

Ringsize Decisions

Ringsize 2 (Updateable):

Enter INDEX install ringsize » 2

✅ Can update later
✅ Owner address is public
✅ Flexible development

Ringsize > 2 (Immutable):

Enter INDEX install ringsize » 16

✅ Maximum privacy/anonymity
✅ Cannot be censored by owner
❌ Cannot be updated (permanent!)

Error Handling

Common Errors

Error: "Invalid DOC1 SCID"

Solution: DOC1 must be a valid TELA-DOC-1 contract
Verify SCID with: » search scid [doc1-scid]

Error: "INDEX size exceeds maximum"

Solution: INDEX is > 11.64KB
1. Reduce number of DOCs
2. Use libraries to consolidate
3. Use DocShards instead of embedding all DOCs

Error: "Cannot update INDEX"

Reasons:
1. Not the contract owner
2. Contract deployed with ringsize > 2 (immutable)
3. Wrong SCID (verify with » search scid)

Error: "MOD validation failed"

Solution:
1. Check MOD tags are valid (» mods)
2. Verify MOD combination allowed (» mod-info [tag])
3. Ensure no conflicting MODs (Single MOD class rule)

Advanced Features

Dynamic Metadata (with MODs)

Update metadata without UpdateCode:

# Requires Variable Store MOD (vsoo, vspubow, etc.)
 
# Update app name
» set-var your-index-scid
Enter key » var_header_name
Enter value » My App v3.0 (Updated!)
 
# Update description
» set-var your-index-scid
Enter key » var_header_description
Enter value » Now with new features!
 
# Add category metadata
» set-var your-index-scid
Enter key » var_meta_category
Enter value » Productivity

Benefits:

❌ Doesn't create new commit version
✅ Instant metadata updates
✅ Lower transaction fees
✅ Useful for status messages

Library Bundles

Create an INDEX that bundles multiple libraries:

// Library bundle INDEX
33 STORE("dURL", "ui-framework.tela.lib")
40 STORE("DOC1", "lib-buttons.scid")     // Button components
41 STORE("DOC2", "lib-forms.scid")       // Form components
42 STORE("DOC3", "lib-modals.scid")      // Modal components
43 STORE("DOC4", "lib-tables.scid")      // Table components

Usage: Other apps can reference this one INDEX SCID to get all libraries

DocShard INDEX

Create an INDEX that reconstructs large files:

// DocShard INDEX (requires .shards in dURL)
33 STORE("dURL", "bigfile.tela.shards")
40 STORE("DOC1", "index.html.scid")       // Regular entrypoint
41 STORE("DOC2", "shard-1.scid")          // Large file shard 1
42 STORE("DOC3", "shard-2.scid")          // Large file shard 2
43 STORE("DOC4", "shard-3.scid")          // Large file shard 3

Auto-reconstruction: TELA detects .shards tag and rebuilds the file
