Creating an L1TxObjective

[NiloCK]

An AA-Nitro SCW requires user Alice and her intermediary Irene to collaborate on submitting her L1 transactions. (more specifically: her UserOperations, which get bundled into L1 transactions by bundlers)

go-nitro can be the driver of these interactions with an L1TxObjective.

tx = someEthTx(); // given some vanilla ethereum transaction...
mySCW = "0xabc";  // the address of my SCW / Ledger Channel
nitroNode.ExecuteTx(mySCW, tx);

Alice's Nitro client creates an objective that:

• converts the tx to a UserOperation
• signs the UserOperation
• forwards the UserOperation to the account intermediary
• waits for the intermediary to signal acceptance / rejection
• if intermediary accepts, you could follow up by watching the chain to see the UserOperation go through

Irene's intermediary Nitro:

• receives the request for an L1tx, which carries a UserOperation signed by Alice
• either:
  • decides that it's "safe" to execute (eg, it doesn't burn account funds that are owned by Irene)
    • Cosigns the UserOperation and submits it to a bundler / the bundling mempool
    • alerts Alice that this has been done
  • decides that it's unsafe, and returns a rejection / failure notice to Alice
