Joining an Auction
Disclaimer: Boardwalk is permissionless. A token appearing in the product is not approval or endorsement from the team.
What contributors deposit
The deposit is the raise token for that chain, not the new token being launched. Think wETH or frxUSD on Fraxtal for example. An auction can accept unlimited deposits during the auction window.
Early participation bonus
Earlier contributions get more weight inside the auction. The bonus starts at 10% at the beginning of the auction and decays to 0% by the end.
For example, a contributor who deposits 1 wETH at the halfway point of a 7-day auction receives a ~5% bonus, so their weighted contribution is ~1.05 wETH for allocation purposes. A contributor who deposits the same 1 wETH in the final minutes receives no bonus. Both deposits count equally toward the graduation threshold.
What happens when the auction ends
The auction window runs for 24 hours on Express launches and 7 days on Advanced launches by default. After the window closes, a 1-hour delay opens before the seeding step becomes available. Once that delay passes, any address can trigger seeding — the process requires no team action or approval.
If the auction reached its graduation threshold, seeding mints the launch’s full token supply and distributes it across the buckets defined by the launch path (see How the supply is split). The seeding call pairs the raised asset with the liquidity allocation in a v2-style pool with a 0.1% swap fee, then burns the LP tokens to the dead address. No address controls the seeded position, and no address can withdraw it. Seeding also initializes LP staking and vesting.
The anti-sniper window activates at the moment of seed (see Post-Launch).
If the auction did not reach its graduation threshold, the same call refunds rather than seeds. Contributors withdraw their full deposit from the contributing address.
When tokens become claimable
After liquidity is seeded and the 7-day claim cliff ends, contributors can claim their allocation of the auction supply.
How allocation is decided
Every Boardwalk launch has a fixed total supply of 10 billion tokens. The auction percentage determines how many of those tokens go to contributors as a group. Each contributor’s allocation equals their weighted contribution (raw deposit times the live bonus multiplier — 1.10 at auction open, decaying to 1.00 at auction close) divided by total weighted contributions in that auction, multiplied by the total contributor token allocation. For example, an Advanced launch with a 30% auction allocation directs 3 billion tokens to contributors. A contributor whose weighted contribution equals 5% of the auction’s total weighted contributions claims 150 million tokens.
