+slug: ../learn-snowbridge

+
+Snowbridge by [Snowfork](https://snowfork.com/) is a general-purpose, trustless bridge between Polkadot and Ethereum. It
+utilizes the [Bridge Hub system parachain](./learn-bridge-hub.md) to establish a connection to its
+relayers, allowing for permissionless messaging between Ethereum and Polkadot.
+
+## Trustlessness in Snowbridge
+
+Trustlessness here is defined in the sense that the users do not need to trust any particular
+individuals or organizations, but rather only the mathematics, code, cryptography, and protocol. An
+example of a system which implies a high level of trust **trust** would be that of a bridge which is
+controlled via a multi-signature scheme, wherein you must trust the cosignatories.
+
+Basic assumptions are always needed in principle when defining a trustless system, as a completely
+trustless setup cannot always be guaranteed.
+
+With Snowbridge, a sender can always run a
+[relayer](https://docs.snowbridge.network/architecture/relayers) to ensure that their cross-chain
+transaction is successful.
+
+## Applications
+
+Snowbridge currently supports
+[two-way token transfers](https://docs.snowbridge.network/applications/token-transfers) between
+Ethereum and Polkadot parachain.
+
+## Accessing & Using Snowbridge
+
+Snowbridge can be accessed through [the web app](https://app.snowbridge.network/), where you may
+track [processing times of transactions,](https://app.snowbridge.network/status),
+[recent transfers](https://app.snowbridge.network/history), and other information about the bridge's
+overall status.
+
+To create transfers, you may visit the [transfer page.](https://app.snowbridge.network/)
