Hi! Thanks for taking time to help us develop the relayer service for expediting CargoX document transactions to the blockchain.

During the next two weeks you will have the opportunity to try out the relaying technologies in order to get familiar with it and make yourself ready for the production environment.

Here's a brief step by step explanation on what each relayer does:

1. Relayer queries the CargoX API to get available signature payloads
2. Encapsulates a payload into a transaction and submits it to the blockchain (spends a bit of matic)
3. For each successfully submitted signature payload (i.e. the relayer is the first one to do so for this signature) the relayer receives some CXO as a reward ($0.30 worth, while $0.30 worth is sent to the 0x000..0 black hole) - provided that the relayer holds enough CXO to be eligible for the reward.

The basic idea is that the amount of Matic spent is less than the received reward, which is compensation for relaying transaction. Similar to mining fees that miners and validators receive.

In order to try this out you will require an Eth private key that you will use on the Mumbai testnet ( https://mumbai.polygonscan.com/ ). We recommend you generate a new random private key. One way is to use an open source tool to do it - e.g. https://vanity-eth.tk/ (Hardware wallets are not recommended because you will need to confirm each transaction manually - you will want to automate your relayer)
Then paste you address in the form below so that we can send you some Test CXO which will be used to mimic the real CXO on the Mumbai testnet.

It is also required that you top up your wallet with some test Matic using this faucet: https://faucet.polygon.technology/

Once you are done please enter the address of your wallet in the form below and we'll be ready to go next week :)
