locklift/src/internal/giver/giverOptions.ts

Node JS framework for working with Ever contracts. Inspired by Truffle and Hardhat. Helps you to build, test, run and maintain your smart contracts.

import { Giver } from "../factory";
import { Address, Contract, ProviderRpcClient, Transaction } from "everscale-inpage-provider";
import { Ed25519KeyPair } from "everscale-standalone-client";

    return this.ever.sendMessage({
      bounce: false,
      amount: value,
      sender: this.account,
      recipient: sendTo,
    });
  }
}

export class TestnetGiver implements Giver {
  public giverContract: Contract<typeof testnetGiverAbi>;

  constructor(ever: ProviderRpcClient, readonly keyPair: Ed25519KeyPair, address: Address) {
    this.giverContract = new ever.Contract(testnetGiverAbi, address);
  }

    sendTo: Address,
    value: string,
  ): Promise<{ transaction: Transaction; output?: Record<string, unknown> }> {

      .sendGrams({
        dest: sendTo,
        amount: value,
      })
      .sendExternal({ publicKey: this.keyPair.publicKey });
  }
}
