relayer-fee-token

Testnet Fungible Token used to cover fees paid by the Relayer in concert with the relayer demo.

FT contract created using https://near.org/contractwizard.near/widget/ContractWizardUI

TODO add shared storage contract option based on https://github.com/NearSocial/social-db/blob/master/contract/src/shared_storage.rs

Pre-requisites

To develop Rust contracts you would need to:

• Install Rustup:

curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh

• Add wasm target to your toolchain:

rustup target add wasm32-unknown-unknown

• Install near-cli

npm install -g near-cli

Build

cargo build --all --target wasm32-unknown-unknown --release

Deploy to Testnet

near dev-deploy --wasmFile target/wasm32-unknown-unknown/release/relayer_fee_token.wasm

Behind the scenes, this is creating an account and deploying a contract to it. On the console, notice a message like:

Done deploying to dev-1234567890123

In this instance, the account is dev-1234567890123. A file has been created containing a key pair to the account, located at neardev/dev-account. To make the next few steps easier, we're going to set an environment variable containing this development account id and use that when copy/pasting commands. Run this command to the environment variable:

source neardev/dev-account.env

You can tell if the environment variable is set correctly if your command line prints the account name after this command:

echo $CONTRACT_NAME

Initialize Contract

The next command will initialize the contract using the new method:

near call $CONTRACT_NAME new --accountId $CONTRACT_NAME

To get the fungible token metadata:

near view $CONTRACT_NAME ft_metadata

Send RFT to another Account (example Bob)

Add storage deposit for your local account:

near call $CONTRACT_NAME storage_deposit '{"account_id": "your_local_credentials_account.testnet"}' --accountId your_local_credentials_account.tesnet --amount 0.25

Mint some RFT to your local account:

near call $CONTRACT_NAME mint '{"amount": "1000000000"}' --accountId your_local_credentials_account.testnet

Check balance of your local account, it should be 1000000000 now:

near view $CONTRACT_NAME ft_balance_of '{"account_id": "bob.testnet"}'

Check balance of Bob's account, it should be 0 for now:

near view $CONTRACT_NAME ft_balance_of '{"account_id": "bob.testnet"}'

Register Bob's account:

near call $CONTRACT_NAME storage_deposit '{"account_id": "bob.testnet"}' --accountId your_local_credentials_account.testnet --amount 0.25

Transfer tokens to Bob from the contract that minted these fungible tokens, exactly 1 yoctoNEAR of deposit should be attached:

near call $CONTRACT_NAME ft_transfer '{"receiver_id": "bob.testnet", "amount": "19"}' --accountId your_local_credentials_account.testnet --amount 0.000000000000000000000001

Check balance of Bob's account again, it should be 19 for now:

near view $CONTRACT_NAME ft_balance_of '{"account_id": "bob.testnet"}'
