Deploying a smart contract

Would you like to contribute to other projects running a validator? Deploy a smart contract on the owner account of a staking pool. This contract will allow users to split their rewards on multiple accounts.

Steps

  • Install cargo and Rust in case you don't have it. This command is for Linux or MacOS.
curl --proto '=https' --tlsv1.2 https://sh.rustup.rs -sSf | sh
source $HOME/.cargo/env
  • Add the wasm32-unknown-unknown toolchain:
rustup target add wasm32-unknown-unknown
  • Clone the project found here:
git clone https://github.com/zavodil/near-staking-pool-owner
  • Compile smart contract:
cd near-staking-pool-owner/contract
cargo build --target wasm32-unknown-unknown --releas
  • Deploy smart contract on your owner account. Adjust the path to .wasm file if required:
NEAR_ENV=shardnet near deploy <OWNER_ID>.shardnet.near --wasmFile target/wasm32-unknown-unknown/release/contract.wasm
  • Initialize the smart contract picking accounts for splitting revenue:
CONTRACT_ID=<OWNER_ID>.shardnet.near
# Change numerator and denomitor to adjust the % for split.
NEAR_ENV=shardnet near call $CONTRACT_ID new '{"staking_pool_account_id": "<STAKINGPOOL_ID>.factory.shardnet.near", "owner_id":"<OWNER_ID>.shardnet.near", "reward_receivers": [["<SPLITED_ACCOUNT_ID_1>.shardnet.near", {"numerator": 3, "denominator":10}], ["<SPLITED_ACCOUNT_ID_2>.shardnet.near", {"numerator": 70, "denominator":100}]]}' --accountId $CONTRACT_ID

Example:

CONTRACT_ID=btcsecure.shardnet.near
NEAR_ENV=shardnet near call $CONTRACT_ID new '{"staking_pool_account_id": "btcsecure.factory.shardnet.near", "owner_id":"btcsecure.shardnet.near", "reward_receivers": [["maelstrom.shardnet.near", {"numerator": 6, "denominator":10}], ["iamamiwhoami.shardnet.near", {"numerator": 40, "denominator":100}]]}' --accountId $CONTRACT_ID
  • Wait until you start receiving rewards on your node staking pool. Do a withdraw of rewards:
CONTRACT_ID=<OWNER_ID>.shardnet.near
NEAR_ENV=shardnet near call $CONTRACT_ID withdraw '{}' --accountId $CONTRACT_ID --gas 200000000000000

Example:

CONTRACT_ID=btcsecure.shardnet.near
NEAR_ENV=shardnet near call $CONTRACT_ID withdraw '{}' --accountId $CONTRACT_ID --gas 200000000000000

  • If you can't open the link in your browser, you can always use Near-CLI:
near tx-status <hash> --accountId <accountid>.shardnet.near

Example:

near tx-status 5Z21wsQCgCFeY3F8xobw85HKUbYsdFjgQFJHavziJC2B --accountId btcsecure.shardnet.near
