How it works

The whole thing fits on one page. Here it is.

A trade

You pick a coin and an amount. Bagday asks Jupiter, the main price router on Solana, for the best route across every exchange and pump.fun's bonding curve. The quote shows what you get, the price impact and the fees.

When you tap buy, Jupiter builds the transaction, your wallet signs it, and it lands on Solana in a few seconds. Bagday never holds your coins at any point. If the price moves too far before it lands, the trade fails and nothing leaves your wallet except the network fee.

Your wallet

Logging in creates a Solana wallet secured by Privy. Only your login can sign with it. You can also link Phantom, Solflare or Backpack. Fund it by sending SOL to the address on your My bags page.

The $BAGDAY buyback

Every 10 minutes, on the UTC clock, Bagday closes a fee window:

Buyback = Bagday's fees in the window × 50%

The buyback buys $BAGDAY on the open market and burns it.

Each buyback gets a receipt with its transaction. $BAGDAY has not launched, so no buyback has happened yet. Read the $BAGDAY page.

The API

The site and the coming mobile app read the same endpoints. Market data is public:

  • GET /api/v1/tokens?list=trending

    A market list: trending, traded, pump or new. Up to 60 coins with price, market cap, volume, holders and safety data.

  • GET /api/v1/tokens/search?q=bonk

    Search by name, ticker or coin address. Up to 20 coins.

  • GET /api/v1/tokens/{mint}

    One coin by its address.

  • GET /api/v1/tokens/{mint}/chart?tf=15m

    Price candles for the coin's main pool: 15m, 1h or 1d.

Trading needs a logged-in session:

  • GET /api/v1/swap/order

    A quote. With a taker wallet it includes the transaction to sign.

  • POST /api/v1/swap/execute

    Sends a signed trade to Solana and returns its signature.

  • GET /api/v1/portfolio?address=…

    A wallet's SOL and coins with live dollar values.

What to know before you buy

  • Most coins lose almost all of their value. Only buy what you can lose.
  • Anyone can make a coin. Bagday lists what Jupiter can route and does not check or endorse any of it.
  • Read the safety signs on each coin page: open minting, freezing, a few wallets holding most of the supply, or a creator who has launched hundreds of coins.
  • Trades on Solana are final. A coin sent to the wrong address is gone.
