Track: realworld. Source: apps/be/src/relay.ts, tests in apps/be/test/relay.test.ts. Owners should not need NEAR for gas to manage their Minds. The relayer accepts a NEP-366 signed delegate action from the signed-in owner and sends it, paying the gas. It is live on the hosted demo for two registry methods, unequip_skill and set_wallet, paid by relayer.hellonear-swarm.testnet, whose only key lives on the server.

​
Limits

  • Only calls to the registry contract, only unequip_skill and set_wallet, with exactly 1 yoctoNEAR attached. A relayer pays any inner deposit too, so methods that need storage or a price (register_mind, equip_skill) are not relayed.
  • Everything that can be refused is refused before sending: sender is the signed-in account, receiver is the registry, gas, ed25519 signature, expiry within 1000 blocks, full-access key, nonce. A bad request costs no gas.
  • 10 per owner per hour. Not for try-out users.
