How can I send an osmosis swap transaction?
Hi,
I'm currently somehow lost in how to use the cosmjs library. I tried a lot of combinations, but I can't sign and broadcast a osmosis swap transaction.
What I already tried:
- Using Stargate Client
const wallet = await DirectSecp256k1HdWallet.fromMnemonic(this.mnemonic, { prefix: 'osmo' });
const rpcOsmo = 'https://rpc-osmosis.keplr.app';
const registry = new Registry([
...defaultRegistryTypes,
['/osmosis/gamm/swap-exact-amount-in', MsgSwapExactAmountIn],
['osmosis/gamm/swap-exact-amount-in', MsgSwapExactAmountIn], // tried both as typeUrl but both get an error
]);
const osmoClient = await SigningStargateClient.connectWithSigner(rpcOsmo, wallet, {
registry: registry,
});
this.osmoClient.signAndBroadcast(
this.osmoAccount.address,
[
{
typeUrl: '/osmosis/gamm/swap-exact-amount-in',
value: {
sender: 'osmo...',
routes: [
{
poolId: '1',
tokenOutDenom: 'ATOM',
},
],
tokenIn: {
denom: 'OSMO',
amount: '123',
},
tokenOutMinAmount: '123',
},
},
],
{
gas: '1000000',
amount: [
{
amount: '0',
denom: 'uosmos',
},
],
},
''
);
-> TypeError: message.poolId.isZero is not a function
this.osmoClient.signAndBroadcast(
this.osmoAccount.address,
[
{
typeUrl: '/osmosis/gamm/swap-exact-amount-in',
value: MsgSwapExactAmountIn.fromPartial({
sender: 'osmo...',
routes: [
{
poolId: Long.fromNumber(1),
tokenOutDenom: 'ATOM',
},
],
tokenIn: {
denom: 'OSMO',
amount: '123',
},
tokenOutMinAmount: '123',
}),
},
],
{
gas: '1000000',
amount: [
{
amount: '0',
denom: 'uosmos',
},
],
},
''
);
-> Broadcasting transaction failed with code 2 (codespace: sdk). Log: unable to resolve type URL /osmosis/gamm/swap-exact-amount-in: tx parse error So it looks like the rpc endpoint of keplr app does not support this type. Looking at the keplr wallet it looks like they use the old client: SigningCosmosClient
- Second try with the old client
const walletCosmos = await Secp256k1HdWallet.fromMnemonic(this.mnemonic, undefined, 'osmo');
const accountsOsmoCosmos = await walletCosmos.getAccounts();
const lcdOsmo = 'https://lcd-osmosis.keplr.app'; // with the rpc endpoint again errors
const osmoCosmosClient = new SigningCosmosClient(lcdOsmo, this.osmoAccountCosmos.address, walletCosmos);
this.osmoCosmosClient.signAndBroadcast(
[
{
type: 'osmosis/gamm/swap-exact-amount-in',
value: {
sender: 'osmo...',
routes: [
{
poolId: Long.fromNumber(1),
tokenOutDenom: 'ATOM',
},
],
tokenIn: {
denom: 'OSMO',
amount: '123',
},
tokenOutMinAmount: '123',
},
},
],
{
gas: '1000000',
amount: [
{
amount: '0',
denom: 'uosmos',
},
],
},
''
);

As far as I understand is BaseAccount type not supported by the SigningCosmosClient. Does anyone has a running example for custom types?
@Phmager you can look at custom protocodecs - https://github.com/cosmos/cosmjs/blob/main/packages/stargate/CUSTOM_PROTOBUF_CODECS.md
I tried with custom type but got same error Broadcasting transaction failed with code 2 (codespace: sdk). Log: unable to resolve type URL /osmosis/gamm/swap-exact-amount-in: tx parse error.
nvm, found the new tx url from osmosis repo, @Phmager it should be /osmosis.gamm.v1beta1.MsgSwapExactAmountIn
As far as I understand is BaseAccount type not supported [..]
CosmJS only supports connecting to Tendermint RPC for all current backends. The clients from @cosmjs/stargate need to be used. The LCD client in @cosmjs/launchpad was only used for Cosmos SDK 0.37-0.39 chains and will be removed in the next version of CosmJS.

I've documented it here. This uses cosmjs but does a lot to manage the registry, etc.

Did you fix it?
