# PulseSwap Learn Two kinds of guide. The how-tos walk through PulseChain itself, step by step against the app that is actually shipped, with the network values and counts read out of its own configuration. The essays explain the market mechanics behind a swap, sourced to primary references and cited inline. PulseSwap quotes DEXes & aggregators on 17 blockchains at once, and these pages are how that works. ## PulseChain how-tos - **[How to swap on PulseChain](https://pulseswap.io/learn/how-to-swap-on-pulsechain)**: the whole trade, step by step: the two token fields, the route list, slippage, gas, and the errors that come up. - **[How to bridge to PulseChain](https://pulseswap.io/learn/bridge-to-pulsechain)**: two different bridges reach PulseChain. Which is which, the steps for the one in this app, and the fixes when a transfer stalls. - **[Add PulseChain to MetaMask](https://pulseswap.io/learn/add-pulsechain-to-metamask)**: one click, or by hand: the RPC URL, chain ID 369 and currency symbol, verified against the live network. ## How aggregation works - **[What is a DEX aggregator?](https://pulseswap.io/learn/what-is-a-dex-aggregator)**: the definition, how a quote is priced for one size, how an aggregator differs from a DEX, and what measured research says about the prices they get. - **[Aggregator of aggregators](https://pulseswap.io/learn/aggregator-of-aggregators)**: why quoting other aggregators alongside the DEXes themselves is at least as good, what that looks like on PulseChain, and what it does not do. - **[Smart order routing](https://pulseswap.io/learn/smart-order-routing)**: how DEX aggregators rebuilt an equities-market mechanism on-chain, and what to check before accepting a route. Building on PulseSwap instead? The [documentation](https://pulseswap.io/docs) covers the quote API, the SDK and the embeddable widget. --- Canonical HTML page:
