Change in custody providers for Proton

Proton has selected a new cryptocurrency custody platform that will allow for faster and more flexible growth on the Proton blockchain, and we are in the final stages of migrating all of our users to this new platform. This change has important implications for all users, please read the details below.

If you have an existing deposit address for a token on the Bridge at Proton Swap, it will become inactive in early October, 2021. This means that any deposits made to this address after the deactivation date will not be received into your Proton wallet, and sending tokens to an inactive wallet address may result in lost funds at that time. Tokens previously sent to the address and received in your wallet are completely safe and will be unaffected by this change.

We will provide more specific dates for the conversion in the coming weeks.

Once this migration is complete, you will need to obtain a new wallet address for the specific token you want to deposit to your Proton wallet via the Proton Bridge. To do this, simply access the Proton Swap site (https://protonswap.com/bridge/), login to your account, choose the coin you want to deposit, and generate a new wallet address. We recommend deleting old wallet addresses from any other platforms you may use to avoid sending funds to the wrong address.

More context:
This platform change will allow us to adopt common deposit addresses for coins that are issued on the same mainnet, such as Ethereum-based ERC-20 tokens and Binance Smart Chain-based BEP-20 tokens.  It will allow us to offer new wrapped cryptocurrencies that were previously unavailable on the Proton blockchain, while laying the groundwork for additional mainnet integrations in the future.

We understand that this may be an inconvenience for you, but we’re taking this action with the best interest of our users in mind. We believe that making this shift will provide you with a better experience in the future.
