Smart Contracts Deploy

You need to deploy your smart contract for it to be available to users of an MAPO-Relay-Chain. The following MAPO-Relay-Chain is collectively referred to as MAPO.

To deploy a smart contract, you merely send an MAPO coin transaction containing the compiled code of the smart contract without specifying any recipient.


You should understand MAPO networks, transactions and the anatomy of smart contracts before deploying smart contracts.

Deploying a contract also costs MAPO coins (MAPO) since they are stored on the blockchain, so you should be familiar with gas and fees on MAPO.

Finally, you'll need to compile your contract before deploying it, so make sure you've read about compiling smart contracts.



  • your contract's bytecode – this is generated through compilation

  • MAPO coins for gas – you'll set your gas limit like other transactions so be aware that contract deployment needs a lot more gas than a simple MAPO coins transfer

  • a deployment script or plugin

  • access to an MAPO node, either by running your own, connecting to a public node


The specific steps involved will depend on the tooling you use. For an example, check out the Hardhat documentation on deploying your contracts or Truffle documentation on networks and app deployment. These are two of the most popular tools for smart contract deployment, which involve writing a script to handle the deployment steps.

Once deployed, your contract will have an MAPO address.
