Pump.fun opens pairing with any platform tokens; buying new tokens directly boosts the original token’s liquidity pool.

Pump.fun has announced an update to its Custom Pairs feature. Previously, new tokens could only be paired with tokenized stocks or whitelisted tokens, but now they can be paired with any token issued on the platform that is either still on a bonding curve or has graduated to PumpSwap. Tokens that have graduated to Raydium and are not on the whitelist are not currently supported, with exceptions for whitelisted projects like Fartcoin. The official stated that derivative trading of past popular tokens was siphoning attention and liquidity. Under the new mechanism, when purchasing a new token paired with an existing one, funds will first be converted into the paired token before buying the new token, thereby generating buy pressure and deeper liquidity for the original token pool. Currently, pairing depth is limited to one layer, and the pairing relationships of already listed tokens cannot be modified. The platform has also adjusted the fee calculation for multi-hop swaps to prevent fees from stacking up.
