Anvora is a prelaunch-only bonding-curve fundraising protocol on Solana with built-in revenue sharing. A creator launches a campaign; backers buy the campaign’s token on a bonding curve during a fixed trading window; when the window closes, the raised SOL is paid out to the creator. Backers who stake their tokens earn a pro-rata claim on the campaign’s revenue — the staker share of every sell fee, plus anything deposited into the campaign — credited to them as it arrives.

Each campaign mints its own token — named and tickered by its creator, 9 decimals — as a standard, hookless Token-2022 (metadata extensions only), so it stays fully composable. Revenue isn’t tied to simply holding the token — backers opt in by staking, and rewards accrue to the staked positions the program custodies on-chain.

Revenue is shared with stakers, not passive holders. A backer opts in by calling stake, which moves their tokens into the per-campaign stake vault (a program-owned account, seeds ["stake_vault", campaign]) and opens a StakePosition on first stake. Staking is one-way until the campaign closes: unstake is refused before settlement, so a staker cannot ride the rewards and then exit ahead of everyone else. close_position reclaims the position’s rent once it is empty and fully claimed.

Two streams fund the pool: the staker share of every sell fee (1% of each sell, paid into the vault as the sale happens) and whatever anyone deposits via deposit_revenue (during the window and at any time after, always split on arrival).

Distribution uses a per-token reward accumulator (fixed-point): every deposit raises the accumulator by deposit ÷ total staked, and a staker’s claim is their staked amount times the accumulator delta since their last checkpoint, floored to lamports once at credit time. Rounding dust below one lamport per token is carried forward, never lost.

Revenue is assigned the moment it arrives, to whoever is staked at that instant, and claim_revenue is open in both phases — what a late staker misses is everything that came in before them, not the claim itself. Because rewards track an explicit staked balance custodied by the program — rather than a transfer hook watching every wallet — the campaign token is a plain, fully composable Token-2022.

The protocol supports referral attribution. Referral cuts are always carved from the protocol’s own share — creators, stakers and the curve are never diluted. There is a single payout point:

• Settle referrals — the campaign creator’s referrer (recorded immutably at create_campaign) earns 2% of the raised SOL at settle, taken from the protocol’s settlement share.

On-chain, the program only enforces that a referrer is not the creator themselves — who the referrer is, and how attribution is tracked, is the app’s responsibility. The cut is not sent to the referrer’s wallet at settle: it is credited to a referral vault, a PDA derived from the referrer’s key alone, which they drain whenever they like with claim_referral_fees. Settle is permissionless, so no address a creator did not author may sit in its critical path — a poisoned referral link would otherwise be able to freeze a campaign at closing time.

The full Anchor IDL (interface definition — everything the tables above are generated from) is available as JSON. Use it with Anchor’s TypeScript client to integrate against the program directly:

import { Program } from "@coral-xyz/anchor";
import idl from "./anvora.json";

const program = new Program(idl, provider);
// program.methods.buy(tokenAmount, maxSolCost)…
