OTR Smart Contract

You can interact directly with the OTR smart contract to register new tipping coins. Your app can charge an optional fee (up to 10%) when registering tipping symbols. You can find the ABI and contract code at the links below.

The cost for registering a tipping symbol is 250,000 $TN100x on Ham chain

TN100x: 0xE8DD44d0791B73afe9066C3A77721f42d0844bEB

OTR Proxy: 0x0181795609a431A8C39eF020ad58f20fE77E8525

OTR Implementation: 0x87a8a4F4F4c5e1b4de47C36D4c70076E304E7DE4

The main function you will interact with is the register function via the OTR Proxy address. For an example of calling this function from a frontend app see this example.

/// @notice Function used to register new tipping tokens
/// @dev Sender must approve fee before calling this method
/// @param tokenAddress ERC20 token that will be tipped. A new corresponding tipping token contract will be deployed for this token.
/// @param tippingSymbolHash Hashed tipping symbol ie viem.toHex("$TIP")
/// @param bpsFee Optional UI registration fee using basis points ie 10% = 1000
/// @param feeRecipient Optional recipient of UI fee
function register(address tokenAddress, bytes calldata tippingSymbolHash, uint bpsFee, address feeRecipient) public returns (address){
    if(bpsFee > MAX_UI_FEE) {
        revert FeeTooHigh();
    }
    uint fee = REGISTRATION_FEE * bpsFee / 10_000;
    uint costMinusFee = REGISTRATION_FEE - fee;
    IERC20(PAYMENT_TOKEN).transferFrom(msg.sender, FEE_RECEIVER, costMinusFee);
    if(fee > 0) {
        IERC20(PAYMENT_TOKEN).transferFrom(msg.sender, feeRecipient, fee);
    }
    address tippingToken = IFloatiesRegistry(REGISTRY).register(
        IFloatiesRegistry.RegistrationParams({
            token: tokenAddress,
            registrant: tokenAddress,
            floatyHash: tippingSymbolHash
        })
    );

    return tippingToken;
}
