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

nla escrow:create \
  --demand "<demand text>" \
  --amount <amount> \
  --token <token_address> \
  --oracle <oracle_address> \
  [--arbitration-provider "<provider>"] \
  [--arbitration-model "<model>"] \
  [--arbitration-prompt "<prompt>"]

5. Record output

The command outputs an escrow UID (0x...). This UID is needed for fulfillment and collection. Present it clearly to the user and explain next steps.

Key details

Available networks: anvil (local), sepolia, base-sepolia, mainnet. Switch with nla switch <network>.
For local dev, nla dev starts Anvil, deploys contracts, creates mock tokens, and starts the oracle.
Public demo oracle on Sepolia: 0xc5c132B69f57dAAAb75d9ebA86cab504b272Ccbc.

Default arbitration prompt:

Evaluate the fulfillment against the demand and decide whether the demand was validly fulfilled

Demand: {{demand}}

Fulfillment: {{obligation}}

Example

nla escrow:create \
  --demand "Provide a valid proof that P != NP" \
  --amount 1000000 \
  --token 0xa513e6e4b8f2a923d98304ec87f64353c4d5c853 \
  --oracle 0xf39Fd6e51aad88F6F4ce6aB8827279cffFb92266 \
  --arbitration-provider "Anthropic" \
  --arbitration-model "claude-3-5-sonnet-20241022"
