LP-3169: LRC-5169 Client Script URI

Abstract

LRC-5169 enables smart contracts to reference off-chain executable scripts (JavaScript/TypeScript) that provide standardized client-side functionality. This creates a bridge between on-chain contracts and off-chain UI/logic.

Motivation

Smart contracts lack standardized client integration:

Each dApp builds custom frontends
No portable contract interactions
Wallet integration requires manual work

LRC-5169 provides:

Contract-specified client scripts
Portable interaction patterns
Wallet-embeddable functionality

Specification

interface ILRC5169 {
    function scriptURI() external view returns (string[] memory);
    event ScriptUpdate(string[] newScriptURI);
}

Script Format

Scripts at the URI must export standard functions:

export interface ContractScript {
  // Render token card
  render(tokenId: string): HTMLElement;
  
  // Get available actions
  getActions(): Action[];
  
  // Execute action
  executeAction(action: string, params: any): Promise<Transaction>;
}

Research Status

This LP documents ERC-5169 for potential adoption. Implementation priority: Low

Key considerations:

Script hosting and availability
Security of executing off-chain code
Version management
