Transaction Builder API
Base URL:https://builder.snek.fun
The Transaction Builder API produces Snekfun transactions as CBOR and also exposes helper endpoints to sign or submit them. When a Turbo Wallet session is available, the same service can also attach the server-side witness and submit the transaction for you.
