Gas Relayer Contracts

[bh2smith]

Providing contract interface for the methods required in this tutorial. I would have gone with the full ABI, but all the existing tooling seems to be failing.

Example Transaction Sequence

near contract call-function as-transaction nft.kagi.testnet storage_deposit json-args {} prepaid-gas '100.0 Tgas' attached-deposit '1 NEAR'

near contract call-function as-transaction nft.kagi.testnet mint json-args {} prepaid-gas '100.0 Tgas' attached-deposit '0 NEAR'

near contract call-function as-transaction nft.kagi.testnet ckt_approve json-args '{"token_id":"118","account_id":"canhazgas.testnet","msg":""}' prepaid-gas '100.0 Tgas' attached-deposit '0 NEAR'


near contract call-function as-transaction canhazgas.testnet get_paymasters json-args '{"chain_id": "97"}' prepaid-gas '100.000 TeraGas' attached-deposit '0 NEAR' sign-as ethdenver2024.testnet network-config testnet sign-with-keychain send

near contract call-function as-transaction canhazgas.testnet set_paymaster_nonce json-args '{"chain_id": "97","token_id": "1", "nonce": 0}' prepaid-gas '100.000 TeraGas' attached-deposit '0 NEAR' sign-as ethdenver2024.testnet network-config testnet sign-with-keychain send

near contract call-function as-transaction canhazgas.testnet create_transaction json-args '{"transaction_rlp_hex":"ee6180847735940085174876e800825208947f01d9b227593e033bf8d6fc86e634d27aa85568865af3107a400080c0","use_paymaster":true, "token_id": "118"}' prepaid-gas '100.000 TeraGas' attached-deposit '0.5 NEAR' sign-as ethdenver2024.testnet network-config testnet sign-with-keychain send



near contract call-function as-transaction canhazgas.testnet sign_next json-args '{"id":"28"}' prepaid-gas '300.0 Tgas' attached-deposit '0 NEAR' sign-as ethdenver2024.testnet network-config testnet sign-with-keychain send

Result of two calls to sign_next

➜  near-ca git:(remove-BN) ✗ near contract call-function as-transaction canhazgas.testnet sign_next json-args '{"id":"30"}' prepaid-gas '300.0 Tgas' attached-deposit '0 NEAR' sign-as ethdenver2024.testnet network-config testnet sign-with-keychain send

Note that the first of the two rawTxs is not yet mined... was this supposed to be the paymaster funding? Its weird.

Questions

• So many near transactions! Will this get bundled?
  3 to kagi.nft
  5 to canhazgas get_paymasters, set_nonce, create_tx, sign_next (2x)

• What is the intermediary transaction?
  never gets mined...

• How to get ABIs?

Progress here is being kept up to date in the issue: #64

This PR is stale, and will be closed in favour of waiting until that work or some plan has been finalized.
