Contracts on Arc testnet

Vestiarion moves money on Arc testnet through two contracts of its own, which each workspace deploys for itself, and through contracts Circle runs. Every address below opens on Arcscan.

Vestiarion's contracts#

Both were written for Vestiarion and are not audited. Their source is in the repository's contracts/ folder, compiled with Solidity 0.8.37, the optimizer on at 200 runs, for the paris EVM version. A workspace that uses one gets its own copy, deployed through Circle's Smart Contract Platform from a deployer wallet of its own. The app shows the copy's address: the escrow's on Contractors → Milestone escrow, and the spending limit's, with the agent's wallet, on Treasury, under the agent's spending limit, On Arc.

VestiarionEscrow#

Locks a milestone's USDC for a contractor before the work starts. See Lock a milestone in escrow.

• Only the workspace's operating wallet, the payer, can call it.
• fund(id, payee, amount, refundAfter) locks an amount for a payee. release(id) pays it to that payee. refund(id) returns it to the payer, and only from refundAfter. Each hold ends once, released or refunded.
• It has no owner and cannot be upgraded.
• It emits Funded, Released and Refunded.
• An owner or admin deploys it with Set up escrow, signed in the ledger as escrow_deployed.

VestiarionSpendingLimit#

Makes the agent's spending limit binding on Arc. See Enforce the limit on Arc.

• The agent's payments leave the operating wallet through pay(to, amount, ref), and only through it: the agent's own wallet holds no money. The operating wallet approves the contract for what it may draw.
• pay refuses anything past the daily figure (the current UTC day) or the 7-day figure (that day and the six before it), and pays each ref once.
• Only its owner, the operating wallet, changes the figures, with setLimits. It cannot be upgraded.
• It emits Paid and LimitsSet. spentToday() and spentThisWeek() read what it paid.
• An owner or admin deploys it with Enforce on Arc, signed in the ledger as spending_limit_enforced.

Deployed#

Both run in production in testnet-2, our own test workspace:

A payee on another chain is paid in that chain's USDC:
