To deploy a Rialto frontend, below json config file is a good example for Rialto (Anvil <--> BSC Testnet).

Rialto bridge cli

Build cb-sol-cli

We can also use the Rialto Bridge contract CLI to interact with the contracts. Grab and install the CLI by running:

git clone -b v1.0.3 --depth 1 https://github.com/FindoraNetwork/chainbridge-tools \
&& cd cb-sol-cli \
&& npm install \
&& make install

Rialto bridge variables

In order to save typing effort, some CLI variables can be setup in the terminal.

export SRC_GATEWAY=https://prod-testnet.prod.findora.org:8545/
export DST_GATEWAY=https://data-seed-prebsc-1-s1.binance.org:8545/
export MY_PK="<your private key>"
export MY_ADDRESS="<your wallet address>"

export SRC_TOKEN="0x0000000000000000000000000000000000001000"
export RESOURCE_ID_FRA="0x000000000000000000000000000000c76ebe4a02bbc34786d860b355f5000000"

export SRC_BRIDGE="0x84a229F67Ca03C4c1e7C3510F1904FA2C088F8D3"
export SRC_HANDLER="0xC44dCe1a28bEB953C730B9964e447f3A429F990b"

export DST_BRIDGE="0x57B76BF81771193548d4190B95c89edF256B8599"
export DST_HANDLER="0xe2b65e624bBb5513fF805d225258D7A92b0f62C4"
export DST_TOKEN="0x112aDd87C7D9cBB7568AEe4b3C1761A1e4385067"

Transfer using CLI (Anvil => BSC Testnet)

Approve

Approve the handler to spend tokens on our behalf (to transfer token to it self).

cb-sol-cli --url $SRC_GATEWAY --privateKey $MY_PK --gasPrice 10000000000 erc20 approve \
    --amount 10 \
    --erc20Address $SRC_TOKEN \
    --recipient $SRC_HANDLER

Note: Most ERC20 contracts use 18 decimal places. The amount specified will be encoded with the necessary decimal places. This can be configured with --decimals on the erc20 command.

Execute a deposit.

cb-sol-cli --url $SRC_GATEWAY --privateKey $MY_PK --gasPrice 10000000000 erc20 deposit \
    --amount 10 \
    --dest 1 \
    --bridge $SRC_BRIDGE \
    --recipient $MY_ADDRESS \
    --resourceId $RESOURCE_ID_FRA

The relayers will wait 3 block confirmations before processing the deposit request which may take a few minutes on Findora network.

Transfer using CLI (BSC Testnet => Anvil)

Approve

Approve the handler on the destination chain to move tokens on our behalf (to burn them).

cb-sol-cli --url $DST_GATEWAY --privateKey $MY_PK --gasPrice 10000000000 erc20 approve \
    --amount 10 \
    --erc20Address $DST_TOKEN \
    --recipient $DST_HANDLER

Execute a deposit.

Transfer the FRA(BEP20) tokens back to the bridge. This should result in the locked tokens being freed on the source chain and returned to your account.

cb-sol-cli --url $DST_GATEWAY --privateKey $MY_PK --gasPrice 10000000000 erc20 deposit \
    --amount 10 \
    --dest 0 \
    --bridge $DST_BRIDGE \
    --recipient $MY_ADDRESS \
    --resourceId $RESOURCE_ID_FRA
