Automating the end user address validation
Pass and validate the end user's wallet address, so they can skip the steps where they have to select and validate their sending/receiving address.
All parameters must be URL encoded. Example:
/37KcpG6mEp+1oAan8/HLEvcfZFXUi6kTOxTHNjD3ZloxS8DL70v7lCmXiEyDOATm4hvewMzBO2d1n25QdJ8WBw=
must be passed as:
%2F37KcpG6mEp%2B1oAan8%2FHLEvcfZFXUi6kTOxTHNjD3ZloxS8DL70v7lCmXiEyDOATm4hvewMzBO2d1n25QdJ8WBw%3D
addr
public address
Allows you to automatically provide the user's receiving or sending public address (the address has to be unique for each user, common addresses are not permitted and will be rejected)
code
4-digits code
Random 4 digits code between 1000 and 9999 that you need to generate for each address supplied with the addr parameter (don't use the same code for all addresses or the validation will be rejected)
hash
#
base64 encoded signature of the following message: MtPelerin-<code>. The private key used to sign the message has to be the one matching the public address given in addr. To test it, see Test vector below.
chain
arbitrum_mainnet avalanche_mainnet
base_mainnet bsc_mainnet celo_mainnet mainnet matic_mainnet optimism_mainnet
rsk_mainnet xdai_mainnet zksync_mainnet
Required to validate the address of a smart contract wallet (EIP1271)
Test vector
You can verify that your signature for the 'hash' parameter is correct by testing it with the following info:
