Questions and answers

A Solana token launchpad, powered by Raydium. Every token launched here gets its own on-chain OTC Liquidity Vault, funded by 50% of BackBid's platform fee. After graduation the vault posts a bid 10% below the lower of the pool's TWAP and spot, and an ask 3% above the higher, within on-chain limits. It never sells into the pool, and it is not a price guarantee. BackBid also has fixed-price OTC offers and buy requests for any Solana token.

How it works

An on-chain account, one per launched token, that collects 50% of that token's SOL fees. After the token graduates, holders can sell to it at the bid (below the pool price) and anyone can buy its tokens at the ask (above the pool price). The spread stays in the vault. No instruction can withdraw its funds.

How the vault works

No. Browsing launches, vaults and OTC offers, searching tokens and reading token pages all work without a wallet. You only connect to launch, trade or post a buy request.

Phantom, Solflare, Backpack and any wallet that supports the Solana Wallet Standard. On mobile, open backbid.fun inside your wallet app's browser; the Sign in window has Open in Phantom and Open in Solflare buttons. On Android Chrome you can also use the Mobile Wallet Adapter.

No. Google is optional: it only signs you in to a BackBid account, so your watchlist, notifications and settings follow you across devices. Your own Solana wallet signs every transaction, and BackBid never holds your keys or your funds. If you sign in with Google, you still connect your wallet and sign with it to launch or trade.

To prove you own the address, so your launches, offers and requests are saved to it. The login message names backbid.fun, is free, isn't a transaction and can't move funds.

Solana mainnet.

Open Launch, enter a name, symbol, image and optional description and links, and sign one transaction. It creates the token on a Raydium bonding curve with a fresh mint address, publishes its metadata, sets up its vault and fee routing, and can include an optional first buy. It costs rent for the token's accounts (≈0.0389 SOL) plus network fees; there's no separate launch fee.

No. The creator fee is 0%. Instead, 50% of every SOL fee goes to the token's own vault, which supports holders, and 50% to the BackBid treasury.

A new token trades on Raydium's bonding curve. When 85 SOL has been raised, Raydium moves it into a Raydium CPMM pool. All of that pool's liquidity is locked forever, so nobody can pull it, and its fees go through the same split as the curve fees. The token's vault opens for trading at graduation.

No. The metadata is referenced on-chain when you launch, and wallets and explorers read it from there. Check the name, symbol and image before you sign.

Yes. The launch transaction can include a first buy at the curve price, paying the normal 1.5% trading fee. It's optional.

On the token's page, use the OTC Vault panel. You get the bid: the lower of the pool's time-weighted average price (TWAP, over 20 minutes) and its spot price, minus the vault's discount (10% by default). The quote shows the exact SOL you'll receive before you sign.

A sale to the vault is refused when:

• the token hasn't graduated yet (on the curve the vault only collects fees);
• it would pay more than 2% of the vault's SOL in one sale (default);
• the daily budget, 10% of the vault's SOL per 24-hour window by default, is spent;
• it would take the vault below its SOL reserve (0.1 SOL by default);
• the vault's tokens would exceed 50% of its total value (default);
• the spot price is more than 15% away from the TWAP (default);
• the vault or the program is paused.

The token page shows the most you can sell right now.

Yes, after graduation, if it holds tokens. You pay the ask: the higher of the TWAP and the spot price, plus the vault's premium (3% by default). Buying from the vault doesn't move the pool price. What you pay goes into the vault.

No instruction can withdraw vault funds: not the admin, not BackBid, not the creator. SOL leaves only as payment to a holder who sells tokens to it, and tokens leave only to a buyer who pays the ask. The admin can pause a vault and tune its parameters within bounds hard-coded in the program. The remaining trust point is the program's upgrade authority, a single wallet held by BackBid's owner (not a multisig), which can deploy new program code; see the Security page.

No. Its bid follows the pool price, so if the price falls, the bid falls too. It can also run out of budget or SOL. The vault promises no price, profit or liquidity.

The current price can be pushed for a moment, even inside one transaction. The TWAP is read from the Raydium pool's own on-chain price history, and a pump and dump within one transaction adds nothing to it. The vault also uses whichever of TWAP and spot is worse for the trader, and refuses trades while they are far apart. Details

On the token's page, use the buy/sell panel. Before graduation you trade on Raydium's bonding curve; after graduation, in its Raydium pool. The quote shows the price impact and fees before you sign, and SOL is wrapped and unwrapped for you in the same transaction.

Match the full mint address (also called CA), not the name or ticker. Anyone can create a token with any name, including here. Each token page shows the mint and links to Solscan. If the mint doesn't match the one the project publishes, don't buy.

Each buy or sell moves the price on the curve or pool. Your slippage setting is the most the price may move against you between the quote and the trade; if it moves more, the transaction fails and nothing is traded.

Fixed-price trading for any Solana token that passes the program's token checks, launched here or not. A seller locks tokens in escrow at one price per token, and buyers take part or all of the offer at that price. Tokens and payment swap in one transaction. Buyers pay 1% and sellers pay 1%.

Open the OTC marketplace

A public post saying "I want X tokens of Y at price Z". Choose Interest only (nothing is locked; it just shows sellers there's demand) or Funded (your SOL/USDC is locked in escrow so any holder can sell to you instantly; cancel anytime to get it back).

You can cancel anytime, and unsold tokens return to your wallet in the same transaction. To change the price, cancel and list again. Nobody else can edit your offer.

Yes. Your offer lives in the escrow program, not on your device, so buyers can fill it at any time and the payment lands in your wallet in the same transaction. A fixed price doesn't follow the market, so check your offer when the price moves.

Any SPL or Token-2022 token, except tokens whose creator can still freeze holders' tokens (active freeze authority), tokens with a transfer fee, permanent delegate or transfer hook, non-transferable tokens, and other uncommon Token-2022 features the escrow doesn't support.

The escrow pays SOL as wrapped SOL (wSOL), a token worth exactly 1 SOL each. Use "Unwrap to SOL" in My offers to turn it back into regular SOL in one transaction.

• Launched tokens on the curve: 1.5% per trade (1.25% BackBid + 0.25% Raydium). Creator fee 0%.
• Vault trades: no platform fee; the spread between bid and ask is the vault's revenue.
• OTC: buyers pay 1% on top of the price, sellers pay 1% from what they receive. Listing pays a deposit (0.0031 SOL) that is refunded when the offer closes.
• Launching: rent for the token's accounts (≈0.0389 SOL).

Solana network fees apply to every transaction. Fee details

Launch fees are split on-chain: 50% to the token's own vault, the rest to the BackBid treasury. OTC fees go to the treasury. A token's vault share is fixed at launch and can never change for that token. The treasury address is on the Fees page.

BackBid never holds your keys; your wallet signs every transaction, after a review with a simulation. Vault funds and escrowed tokens are held by program accounts that can only move them under fixed rules.

There are still real risks. The program is not audited, and smart contracts can have bugs. The program's upgrade authority, a single wallet held by BackBid's owner, could change its rules. Memecoins can lose most of their value quickly, and a vault may not be able to buy from you. Only use amounts you can afford to lose. Risks and the Security page.

No, not audited. The BackBid program has not been reviewed by an independent security firm. Smart contracts can have bugs, so only use amounts you can afford to lose.

No. At graduation, all of the pool's liquidity is locked forever in Raydium's LP lock. Only its fees can be claimed, by the token's program address, and they go to the vault and the treasury. The creator can still sell tokens they hold, like anyone else.

• Mint authority: the creator can print more tokens.
• Freeze authority: the creator can freeze your tokens so you can't sell them.
• Transfer fee / transfer hook: the token takes a cut of transfers, or can block them.
• Top-10 holders: how concentrated the supply is.
• Red badges are serious; read them before you buy.

To report a token or offer, use "Report" on the offer or token page while signed in. BackBid will never DM you first or ask for your seed phrase.
