BNS Airdrop

This is a sample contract that realizes the airdrop functionality. The smart contract is built on CosmWasm library and dedicated to terra ecosystem (tested on LocalTerra only).

Build the contract

cargo run-script optimize

Interacting with the Contract

Deploy contract to local-terra blockchain:

terracli tx wasm store artifacts/bns_airdrop.wasm --from test1 --chain-id=localterra --gas=auto --fees=100000uluna --broadcast-mode=block

Create a contract instance

• code_id - id of the deployed contract;
• owner - human address of the contract owner (admin);
• token - human address of the token contract;

terracli tx wasm instantiate <code_id> '{"owner": "<owner_address>", "token": "<token_address>"}' --from test1 --chain-id=localterra --fees=10000uluna --gas=auto --broadcast-mode=block

Register the merkle tree root

• contract_address;
• merkle_root;

terracli tx wasm execute <contract_address> '{"merkle_root": {"node": "<merkle_root>"} }' --from test1 --chain-id=localterra --fees=1000000uluna --gas=auto --broadcast-mode=block

Query

• contract_address;
• claim_address;
• stage_index;

terracli query wasm contract-store <contract_address> '{"merkle_root": {"stage_index": <stage_index>}}'

terracli query wasm contract-store <contract_address> '{"is_claimed": {"stage_index": 1, "address": "<claim_address>" }}'

Claim airdrop

terracli tx wasm execute <contract_address> '{"claim": {"stage_index": 1, "amount": "1111", "proof": ["9446abab3c6c205e08648131ed635e9fd53cb58ecc495eeb98e20bb5ddde8e75", "ba6494fc293a91a73a7ee94d31beba417ed5ad43a648227613920c39237f77bc"]}}' --from test1 --chain-id=localterra --fees=1000000uluna --gas=auto --broadcast-mode=block
