Tool for generating offline permits for bounty hunters to withdraw their payments.
Create a .env file in the project root:
# common variables
CHAIN_ID="" # mainnet: 1, goerli: 5
FRONTEND_URL=""
UBIQUIBOT_PRIVATE_KEY=""
RPC_PROVIDER_URL=""
PAYMENT_TOKEN_ADDRESS="" # // DAI address, mainnet: 0x6b175474e89094c44da98b954eedeac495271d0f, goerli: 0x11fE4B6AE13d2a6055C8D9cF65c55bac32B5d844
# variables depending on spender (bounty hunter)
AMOUNT_IN_ETH="1" # amount in ether, 1 AMOUNT_IN_ETH = 1000000000000000000 WEI
BENEFICIARY_ADDRESS=""
- Admin sets
env.AMOUNT_IN_ETHandenv.BENEFICIARY_ADDRESSdepending on a bounty hunter's reward and address - Admin generates an offline permit URL via
npx tsx generate-permit2-url.ts. Permit URL example:

- Admin posts offline permit URL in issue comments
- Bounty hunter opens permit URL, connects wallet and clicks a "withdraw" button to get a payment
- Set
.envvariables. - Run
anvil --chain-id 31337 --fork-url https://rpc.gnosis.gateway.fmin a separate terminal. - Run the Anvil commands (uses the Anvil default wallets).
- In the project root run
yarn start. - A permit URL for both ERC20 and ERC721 is generated in the terminal.
- Open the generated permit URL defaulting to the variable values in the
.envfile. - Connect the bounty hunter's address.
- Click the "withdraw" button to get a reward.
- Testing the ERC721 permit is easiest deploying the
nft-rewardscontract from the repository

This section describes how to invalidate the following permit (i.e. invalidate a permit2 nonce)
- Setup
.envfile with the required env variables:NONCE(nonce number),NONCE_SIGNER_ADDRESS(i.e. the bot's wallet) andRPC_PROVIDER_URL. For this permit URL the.envfile will look like this:
NONCE="9867970486646789738815952475601005014850694197864057371518032581271992954680"
NONCE_SIGNER_ADDRESS="0xf87ca4583C792212e52720d127E7E0A38B818aD1"
RPC_PROVIDER_URL="https://rpc.ankr.com/gnosis"
- Run
yarn nonce:get-invalidate-params. You will get this output:
== Logs ==
Is nonce used: false

- Open https://gnosisscan.io/address/0x000000000022D473030F116dDEE9F6B43aC78BA3#writeContract and connect your wallet
- Call
invalidateUnorderedNonces()with thewordPosandmaskparams you got on step 2
Notice that this examples uses gnosis chain for nonce invalidation. If you need to invalidate nonce on some other chain then:
- Set
RPC_PROVIDER_URLon step 1 to the desired RPC chain provider - On step 3 open UI for the desired chain
