Implementation Reference

• index.js:103-149 (registration)

  Registration of the 'distributeNative' tool using server.tool(), including inline schema and handler function.

  server.tool(
    'distributeNative',
    'Send BNB to multiple addresses on BSC using the C98MultiSend contract.',
    z.object({
      receivers: z.array(z.string().refine((val) => ethers.isAddress(val), {
        message: 'Invalid BSC address'
      })).describe('Array of BSC addresses to receive BNB.'),
      amounts: z.array(z.number().positive('Amount must be positive')).describe('Array of BNB amounts (in BNB, e.g., 0.1) to send to each receiver.')
    }),
    async ({ receivers, amounts }) => {
      try {
        // Validate inputs
        if (receivers.length !== amounts.length) {
          return {
            content: [{ type: 'text', text: 'Receivers and amounts arrays must have the same length' }],
            isError: true
          };
        }
  
        // Convert amounts to wei and calculate total
        const amountsWei = amounts.map(amount => ethers.parseEther(amount.toString()));
        const totalAmountWei = amountsWei.reduce((sum, amount) => sum + BigInt(amount), BigInt(0));
  
        // Prepare and send transaction
        const tx = await contract.transferMulti(receivers, amountsWei, {
          value: totalAmountWei,
          gasLimit: await contract.transferMulti.estimateGas(receivers, amountsWei, { value: totalAmountWei })
        });
  
        // Wait for transaction confirmation
        const receipt = await tx.wait();
  
        return {
          content: [{
            type: 'text',
            text: `BNB distribution successful. Tx Hash: ${receipt.hash}`
          }],
          isError: false
        };
      } catch (error) {
        return {
          content: [{ type: 'text', text: `Error executing BNB distribution: ${error.message}` }],
          isError: true
        };
      }
    }
  );

• index.js:112-148 (handler)

  Handler function that validates inputs, converts amounts to wei, calls contract.transferMulti to distribute BNB, and returns success or error response.

  async ({ receivers, amounts }) => {
    try {
      // Validate inputs
      if (receivers.length !== amounts.length) {
        return {
          content: [{ type: 'text', text: 'Receivers and amounts arrays must have the same length' }],
          isError: true
        };
      }
  
      // Convert amounts to wei and calculate total
      const amountsWei = amounts.map(amount => ethers.parseEther(amount.toString()));
      const totalAmountWei = amountsWei.reduce((sum, amount) => sum + BigInt(amount), BigInt(0));
  
      // Prepare and send transaction
      const tx = await contract.transferMulti(receivers, amountsWei, {
        value: totalAmountWei,
        gasLimit: await contract.transferMulti.estimateGas(receivers, amountsWei, { value: totalAmountWei })
      });
  
      // Wait for transaction confirmation
      const receipt = await tx.wait();
  
      return {
        content: [{
          type: 'text',
          text: `BNB distribution successful. Tx Hash: ${receipt.hash}`
        }],
        isError: false
      };
    } catch (error) {
      return {
        content: [{ type: 'text', text: `Error executing BNB distribution: ${error.message}` }],
        isError: true
      };
    }
  }

• index.js:106-111 (schema)

  Zod schema defining the input parameters: arrays of receiver addresses and BNB amounts with validation.

  z.object({
    receivers: z.array(z.string().refine((val) => ethers.isAddress(val), {
      message: 'Invalid BSC address'
    })).describe('Array of BSC addresses to receive BNB.'),
    amounts: z.array(z.number().positive('Amount must be positive')).describe('Array of BNB amounts (in BNB, e.g., 0.1) to send to each receiver.')
  }),
