Other than initializing a client instance, no specific setup is required. However, if your application generates a high volume of requests it is suggested that you setup your own Algod node. See the links below for more information:
Default clients connect to Algod nodes maintained by AlgoNode.io (Thanks AlgoNode!). It's important that your application handle rate limiting (HTTP 429) responses by decreasing the frequency of requests. See this guide for a discussion on the topic.
Swap one asset for another in an existing pool.
// Initialize the client
var client = new TinymanV2TestnetClient(); // or TinymanV1TestnetClient();
// Get the assets
var tinyUsdc = await client.FetchAssetAsync(21582668);
var algo = await client.FetchAssetAsync(0);
// Get the pool
var pool = await client.FetchPoolAsync(algo, tinyUsdc);
// Get a quote to swap 1 Algo for tinyUsdc
var amountIn = Algorand.Utils.Utils.AlgosToMicroalgos(1.0);
var quote = pool.CalculateFixedInputSwapQuote(new AssetAmount(algo, amountIn), 0.005);
// Perform the swap
var result = await client.SwapAsync(account, quote);Add assets to an existing pool in exchange for the liquidity pool asset.
// Initialize the client
var client = new TinymanV2TestnetClient(); // or TinymanV1TestnetClient();
// Get the assets
var tinyUsdc = await client.FetchAssetAsync(21582668);
var algo = await client.FetchAssetAsync(0);
// Get the pool
var pool = await client.FetchPoolAsync(algo, tinyUsdc);
// Get a quote to add 1 Algo and the corresponding tinyUsdc amount to the pool
var amountIn = Algorand.Utils.Utils.AlgosToMicroalgos(1.0);
var quote = pool.CalculateMintQuote(new AssetAmount(algo, amountIn), 0.005);
// Perform the minting
var result = await client.MintAsync(account, quote);Exchange the liquidity pool asset for the pool assets.
// Initialize the client
var client = new TinymanV2TestnetClient(); // or TinymanV1TestnetClient();
// Get the assets
var tinyUsdc = await client.FetchAssetAsync(21582668);
var algo = await client.FetchAssetAsync(0);
// Get the pool
var pool = await client.FetchPoolAsync(algo, tinyUsdc);
// Get a quote to swap the entire liquidity pool asset balance for pooled assets
var amount = client.GetBalance(account.Address, pool.LiquidityAsset);
var quote = pool.CalculateBurnQuote(amount, 0.005);
// Perform the burning
var result = await client.BurnAsync(account, quote);Redeem excess amounts from previous transactions.
// Initialize the client
var client = new TinymanV1TestnetClient();
// Fetch the amounts
var excessAmounts = await client.FetchExcessAmountsAsync(account.Address);
// Redeem each amount
foreach (var quote in excessAmounts) {
var result = await client.RedeemAsync(account, quote);
