Chains and prices

These tables are generated from the live agent.json, so they match what Lasso serves and charges. When you need a value at runtime, read agent.json directly.

curl -fsSL https://lasso.sh/agent.json | jq '.chains, .pricing'

Chains

Use the name or the chain ID as the <chain> segment of an RPC URL. Your Custom profiles can serve any EVM chain your providers serve.

Chain name	Chain ID
`ethereum`	1
`optimism`	10
`bsc`	56
`unichain`	130
`polygon`	137
`world`	480
`tempo`	4217
`robinhood`	4663
`base`	8453
`arbitrum`	42161
`tempo-testnet`	42431
`base-sepolia`	84532
`arbitrum-sepolia`	421614
`ethereum-sepolia`	11155111

Request prices

The USD price of one request on premium providers, by method and strategy. Requests served on public providers or Custom profiles have no request price. A batch is priced per item, and each WebSocket subscription notification is priced as an eth_subscription request.

Limits

A method’s presence here is its price, not a promise that every provider in the pool serves it. See RPC method behavior.
Prices can change; a purchase is always held to the terms in the challenge you signed.
