How to Migrate from v0.20.x

You can find working code snippets here.

Compress

// old
const activeStateTrees = await connection.getCachedActiveStateTreeInfo();
const { tree } = pickRandomTreeAndQueue(activeStateTrees);

const compressIx = await CompressedTokenProgram.compress({
    outputStateTree: tree,
});


// New
const treeInfos = await rpc.getStateTreeInfos();
const treeInfo = selectStateTreeInfo(treeInfos);

const infos = await getTokenPoolInfos(rpc, mint);
const tokenPoolInfo = selectTokenPoolInfo(infos);

const compressIx = await CompressedTokenProgram.compress({
    outputStateTreeInfo: treeInfo,
    tokenPoolInfo,
});

Decompress

Old (v0.20.x)

// ...

const stateTreeInfos = await rpc.getCachedActiveStateTreeInfo();
const { tree } = pickRandomTreeAndQueue(stateTreeInfos)

const ix = await CompressedTokenProgram.decompress({
    ...rest,
    outputStateTree: tree,
});

New (v0.21.x)

// ...

const poolInfos = await getTokenPoolInfos(rpc, mint);
const selectedTokenPoolInfos = selectTokenPoolInfosForDecompression(
    poolInfos,
    amount,
);

const ix = await CompressedTokenProgram.decompress({
    ...rest
    tokenPoolInfos: selectedTokenPoolInfos,
});
