New tokens on Raydium LaunchLab, streamed

Raydium LaunchLab is the bonding-curve program that launchpads such as bonk.fun and StonkFun run on. Our feed decodes every LaunchLab launch, trade and migration, whichever launchpad it came through, and tells you which platform configuration it used.

Market data only. New tokens are high risk; this data says what happened on chain, not what to buy.

Decoded by our feed from a recorded mainnet transaction (replayed, so source reads replay; live events say geyser).

• mint is the new token; curve its LaunchLab pool; creator the wallet that launched it. name, symbol and uri come from the launch itself.
• x.platform_config is the launchpad's platform configuration account. x.platform names it where we have mapped that configuration (for example stonkfun, higgspad); otherwise it is an empty string and platform_config is the identifier to use.
• base_flags may be null on a brand-new mint while we read it; later events carry it (see Token-2022 risk flags).

Captured from our live feed on 2026-10-07.

• is_buy: the user received the launched token. Amounts are what the user paid and received, as strings of raw units.
• fees splits protocol, platform, creator and share fees.
• x carries the curve state after the trade: virtual_base / virtual_quote, real_base_after / real_quote_after, and pool_status.
• via is the outer program when the trade came through a router.
• The quote is whatever the platform configured, not always SOL; this one's base mint also carries a Token-2022 transfer fee, shown in base_flags.transfer_fee.

Graduation

When a LaunchLab curve fills, the token migrates to raydium_cpmm or raydium_v4, and you receive a migration message with the new pool. See migration events for its fields.
