gnomic_airdrop package

Overview

Claim-based airdrop realm with Merkle proofs.

Why Merkle rather than an on-chain list:

  • the beneficiary list can run to tens of thousands of rows; writing it on-chain costs gas and storage deposit in proportion;
  • here only 32 bytes go on-chain (the root), plus one record per ACTUAL claim. Whoever never claims costs nothing.

Operating flow:

  1. deploy this realm;
  2. fund it by transferring GRC20 tokens to it (its address is returned by RealmAddress());
  3. the admin publishes root, leaf count and deadline block with SetCampaign;
  4. each beneficiary calls Claim with their own proof;
  5. after the deadline the admin recovers the residue with Sweep.

The Merkle leaf is the string "<address>|<amount in base units>", UTF-8 encoded. The tree is Tendermint's "simple tree" (gno's crypto/merkle): leaf = SHA256(0x00||data), node = SHA256(0x01||left||right), split at the largest power of two below n. The generator in tools/merkle produces compatible proofs.

Ask AI Claude ChatGPT

ClaimInstant is the first of the two alternatives to Claim: the instant share (instantBps, 30%) is paid at once and the rest (70%) is given up the same way a forfeit is — half burned, half to the ecosystem fund — whenever it is chosen, even after the whole grant would have vested. The share is larger than Claim's immediate 10% on purpose: it makes the shortcut a real choice rather than a punishment. It cannot be undone and suits someone who prefers a certain fraction today to the whole a year from now. The residue is destroyed, to every holder's benefit.

Only the person concerned can choose it: there is no "on behalf of" form.
