Data Providers

Mock

const mockProvider: BaseDataProvider = new MockDataProvider();

Blockfrost

Dexter requires a lot of requests when pulling liquidity pools, so it is advised to either host your own Blockfrost backend, or use an API plan sufficient to handle enough requests.

const blockfrostProvider: BaseDataProvider = new BlockfrostProvider(
    {
        url: 'https://cardano-mainnet.blockfrost.io/api/v0',
        projectId: '<blockfrost-project-id>',
    }
);

Kupo

const kupoProvider: BaseDataProvider = new KupoProvider(
    {
        url: 'http://localhost:1442',
    }
);

For the best results, the matching patterns below give the minimum required for DEX addresses to resolve within Dexter :

--match "de9b756719341e79785aa13c164e7fe68c189ed04d61c9876b2fe53f.4d7565736c69537761705f414d4d"
--match "026a18d04a0c642759bb3d83b12e3344894e5c1c7b2aeb1a2113a570.4c"

--match "addr1w9qzpelu9hn45pefc0xr4ac4kdxeswq7pndul2vuj59u8tqaxdznu"
--match "{ Your Address }"
