Note that the max limit is 1000 for this engine. Defaults to 200, maximum is 2000. We limit looking ahead to 20 addresses; if more than 20 addresses are skipped for the next to an HD Wallet, it wont be detected/added to the HD Wallet. (e.g., IP addresses) Reach out to us to discuss custom endpoints. Transaction Hash Endpoint curl "block_hash " c504bdea36e5. In simpler terms, if an unconfirmed transaction returns a confidence factor.9, then our data says theres.1 chance that an attempted double-spend will succeed.

The other supported client SDKs batch differently, but each idiomatic to their respective language (check the code pane examples in each library). If you set public metadata, you cannot modify or delete. Digital signing can be a difficult process, and is where the majority of issues arise when dealing with cryptocurrency transactions. On the BlockCypher Test Chain, the faucet will refuse to fund an address with more than 500 billion BlockCypher satoshis and will not fund more than 100 million BlockCypher satoshis at a time.

Size integer bitcoin testnet address version Optional Raw size of block (including header and all transactions) in bytes.
Finally, we only offer the option of passing private keys because we understand that signing on the client side can be difficult, depending on the environment.

The private key method doesnt work with uncompressed public addresses as sources.
A Wallet contains a list of addresses associated by its name and the users token. As you can see from the code example, you only need to provide a single public address within the addresses array of both the input and output of your TX request bitcoin testnet address version object. All you need is the data you want to embed (up to 40 bytes, inclusive) and well handle the rest. Confidence integer Filters response to only include TXs above confidence in percent;.g., if this is set to 99, will only return TXs with 99 confidence or above (including all confirmed TXs). Otherwise, your generated private keys will be sent over insecure channels and could be mitmd.
