Syntax

exchange.IO("dexes", ...)

When called as exchange.IO("dexes", ...), this function restricts the liquidity sources that swaps go through on a Jupiter exchange object, for example to trade only on pump.fun, Meteora or Raydium.


    
    
    
exchange.IO(k)


    
    
    
exchange.IO(k, sources)

Examples

Trade a new token on pump.fun only.


    javascript
    
    
function main() {
    exchange.IO("dexes", "pump")
    exchange.IO("token", "POUT", "DB5QKorV9KHY54y73h5xWQqYyuD8P3jC1p5Ea8DBpump")
    var t = exchange.GetTicker("POUT_SOL")
    Log("Bid", t.Buy, "Ask", t.Sell, "via", t.Info.askRoute)
}

Returns

Type	Description
array / null value	Returns the array of source names currently in effect (groups expanded; an empty array means no restriction). If a source name is not in Jupiter's source table, a null value is returned, the setting is left unchanged, and `GetLastError()` lists the available source names.

Arguments

Name	Type	Required	Description
k	string	Yes	Selects what the `exchange.IO()` function does. Set it to `dexes` to restrict the liquidity sources.
sources	string	No	Comma-separated list of sources. It can use the group shorthands `pump` (Pump.fun, Pump.fun Amm), `meteora` (Meteora, Meteora DAMM v2, Meteora DLMM), `raydium` (Raydium, Raydium CLMM, Raydium CP, Raydium Launchlab) and `orca` (Whirlpool, Orca V1, Orca V2), or Jupiter source names (case-sensitive). An empty string `""` removes the restriction. Omit it to query the current setting.
