Compatibility

Bitcoin and Omnilayer addresses

For onchain transactions, the receiving address of omni assets must be p2pkh, that is:

1. Mainnet: address starting with 1
2. Testnet: address starting with 'm' or 'n'
3. Regtest: address starting with 'm' or 'n'

BECH32 addresses(pubkey hash or script hash starting with bc1 on mainnet, tb1 on testnet) are not supported(OmniBOLT 2), and sending omni assets to BECH32 addresses will result in permanent fund loss. OBAndroid protects users from such dangerous operations.

Bitcoin transactions support all legal BTC receiving addresses, including bech32 (starting with bc) addresses.

Invoice format

The currently supported invoice format is OmniBOLT 7.

BOLT 11 lacks asset awareness and is not supported by OBAndroid at this stage, paying BTC/satoshi to a BOLT 11 invoice will cause the payment to fail.

obd and lnd versions

Full OBAndroid functionality depends on running a certain version of obd on mobile devices. View the table below to ensure that you run the correct version of obd with the relevant OBAndroid release. The bundled version will always come with the correct, compatible versioning. To connect to remote obd nodes, you should check the compatibility dependency below.
