Meta-transaction relayer: HelloNear pays the gas for an owner's signed registry call (NEP-366)
The owner signs a delegate action in their own NEAR wallet; the relayer wraps it in a transaction and pays the gas. Only for REGISTRY_CONTRACT_ID, only unequip_skill and set_wallet with exactly 1 yoctoNEAR (the relayer would pay any deposit), at most 4 calls of at most 30 Tgas, a full-access key, a nonce above the key’s, and an expiry at most 1000 blocks ahead. 10 per owner per hour.
