Implementation Reference

• src/index.ts:406-443 (registration)

  Tool registration in getAvailableTools() including name, description, and input schema for deploy_erc20_token
  { name: 'deploy_erc20_token', description: 'Deploy a new ERC20 token contract', inputSchema: { type: 'object', properties: { name: { type: 'string', description: 'Token name (e.g., "My Token")', }, symbol: { type: 'string', description: 'Token symbol (e.g., "MTK")', }, decimals: { type: 'number', description: 'Token decimals (default: 18)', }, initialSupply: { type: 'string', description: 'Initial token supply', }, mintable: { type: 'boolean', description: 'Whether the token should be mintable (default: false)', }, gasLimit: { type: 'string', description: 'Optional gas limit', }, gasPrice: { type: 'string', description: 'Optional gas price', }, }, required: ['name', 'symbol', 'initialSupply'], }, },
• src/index.ts:850-879 (handler)

  MCP server handler that gets current wallet, calls rootstockClient.deployERC20Token, and formats success response with explorer links
  private async handleDeployERC20Token(params: DeployERC20Params) { try { const wallet = this.walletManager.getCurrentWallet(); const result = await this.rootstockClient.deployERC20Token( wallet, params.name, params.symbol, params.decimals || 18, params.initialSupply, params.mintable || false, params.gasLimit, params.gasPrice ); const explorerUrl = this.rootstockClient.getExplorerUrl(); const contractExplorerLink = `${explorerUrl}/address/${result.contractAddress}`; const txExplorerLink = `${explorerUrl}/tx/${result.transactionHash}`; return { content: [ { type: 'text', text: `ERC20 Token Deployed Successfully!\n\nContract Address: ${result.contractAddress}\nContract Explorer: ${contractExplorerLink}\n\nTransaction Hash: ${result.transactionHash}\nTransaction Explorer: ${txExplorerLink}\n\nToken Details:\nName: ${result.name}\nSymbol: ${result.symbol}\nDecimals: ${result.decimals}\nInitial Supply: ${result.initialSupply}\nDeployer: ${result.deployer}\nGas Used: ${result.gasUsed}\nBlock Number: ${result.blockNumber}`, }, ], }; } catch (error) { throw new Error(`Failed to deploy ERC20 token: ${error}`); } }
• src/rootstock-client.ts:406-489 (handler)

  Core deployment logic in RootstockClient: checks balance, loads pre-compiled contract bytecode/ABI based on mintable, deploys via ethers.ContractFactory.deploy(name, symbol, initialSupply, decimals), waits for receipt, returns contract details
  async deployERC20Token( wallet: ethers.Wallet | ethers.HDNodeWallet, name: string, symbol: string, decimals: number = 18, initialSupply: string, mintable: boolean = false, gasLimit?: string, gasPrice?: string ): Promise<{ contractAddress: string; transactionHash: string; name: string; symbol: string; decimals: number; initialSupply: string; deployer: string; gasUsed?: string; blockNumber?: number; }> { try { const connectedWallet = wallet.connect(this.getProvider()); // Check wallet balance first const balance = await this.getProvider().getBalance(wallet.address); console.log(`Wallet balance: ${ethers.formatEther(balance)} ${this.getCurrencySymbol()}`); if (balance === 0n) { throw new Error(`Wallet has no funds for deployment. Please fund the wallet: ${wallet.address}`); } // Get pre-compiled contract console.log('Loading ERC20 contract...'); const compiled = this.getCompiledERC20Contract(mintable); console.log('Contract loaded successfully'); // Create contract factory const contractFactory = new ethers.ContractFactory( compiled.abi, compiled.bytecode, connectedWallet ); // Parse initial supply (raw number, contract handles decimals) const parsedInitialSupply = BigInt(initialSupply); console.log(`Deploying contract with initial supply: ${parsedInitialSupply.toString()}`); // Deploy contract with Hyperion-compatible parameters: name, symbol, initialSupply, decimals const contract = await contractFactory.deploy( name, symbol, parsedInitialSupply, decimals, { gasLimit: gasLimit ? BigInt(gasLimit) : undefined, gasPrice: gasPrice ? BigInt(gasPrice) : undefined, } ); console.log('Contract deployment transaction sent, waiting for confirmation...'); // Wait for deployment const receipt = await contract.deploymentTransaction()?.wait(); console.log('Contract deployed successfully!'); const contractAddress = await contract.getAddress(); console.log(`Contract address: ${contractAddress}`); return { contractAddress, transactionHash: contract.deploymentTransaction()?.hash || '', name, symbol, decimals, initialSupply, deployer: wallet.address, gasUsed: receipt?.gasUsed.toString(), blockNumber: receipt?.blockNumber, }; } catch (error) { console.error('Deployment error:', error); throw new Error(`Failed to deploy ERC20 token: ${error}`); } }
• src/rootstock-client.ts:882-895 (helper)

  Helper that returns ABI and hardcoded bytecode for standard or mintable ERC20 contract used in deployment
  private getCompiledERC20Contract(mintable: boolean): { abi: string[], bytecode: string } { // Use the working Hyperion-compatible bytecode directly if (mintable) { return { abi:
