Create NLA Escrow

Help the user create a blockchain escrow backed by a natural language demand using the nla CLI.

Overview

An NLA escrow locks ERC20 tokens on-chain. Anyone can attempt to fulfill the escrow's natural language demand. An AI oracle evaluates fulfillments and releases the tokens if the demand is satisfied.

Step-by-step instructions

1. Gather requirements

Collect the following from the user conversationally:

Required:

• Demand: The natural language condition that must be fulfilled. Help the user craft something clear and unambiguous.
• Amount: Number of tokens to escrow (in the token's smallest unit - no automatic decimal conversion).
• Token address: ERC20 token contract address (0x...).
• Oracle address: Address of the oracle that will arbitrate.

Optional:

• Arbitration provider: OpenAI (default), Anthropic, or OpenRouter.
• Arbitration model: e.g. gpt-4o-mini (default), claude-3-5-sonnet-20241022, openai/gpt-4o.
• Arbitration prompt: Custom prompt template with {{demand}} and {{obligation}} placeholders.

2. Check prerequisites

# Verify CLI is available
which nla

# Check current network
nla network

# Check wallet is configured
nla wallet:show

If no wallet is configured, the user must either:

• Run nla wallet:set --private-key <key>
• Pass --private-key <key> to the command
• Set the PRIVATE_KEY environment variable

3. Help craft the demand

Guide the user to write an effective demand:

• Be specific and evaluable by an LLM
• Consider: what counts as valid fulfillment? Is the condition verifiable?
• For claims requiring real-world knowledge, suggest models with search (Perplexity search is available if the oracle has it configured)
• The demand, provider, model, and prompt are all encoded on-chain and publicly visible - never include secrets

4. Execute escrow creation
