Create a Bitcoin (BTC) Wallet to Send and Receive Bitcoin
Bitcoin (BTC) is the native cryptocurrency of the Bitcoin network and plays a vital role in securing the network through proof-of-work consensus. Beyond its security function, BTC serves as both a digital store of value and a medium of exchange, widely adopted by individuals, businesses, and institutions.
To interact with the Bitcoin network—such as sending or receiving BTC—users rely on wallet applications. These wallets require direct access to a Bitcoin node to perform core functions like:
- Calculating unspent transaction outputs (UTXOs) for a set of addresses
- Signing transactions securely using private keys
- Broadcasting signed transactions to the network
- Querying historical transaction data
With Amazon Managed Blockchain Access Bitcoin, developers can build wallet services that integrate directly with the Bitcoin mainnet via supported JSON-RPC methods. This eliminates the need to run and maintain costly infrastructure while ensuring low-latency, reliable connectivity.
Key JSON-RPCs supported for wallet functionality include:
estimatesmartfee– Estimate transaction fees based on desired confirmation timecreatemultisig– Generate a multi-signature address for enhanced securitycreaterawtransaction– Construct an unsigned transaction objectsendrawtransaction– Broadcast a signed transaction to the network
These APIs empower developers to implement non-custodial wallets, payment gateways, or institutional custody solutions with ease. By abstracting away node management, AMB enables faster time-to-market and improved scalability.
Analyze Transaction Activity on the Bitcoin Blockchain
Understanding on-chain activity is crucial for analytics platforms, financial institutions, compliance tools, and market researchers. With AMB Access Bitcoin, you can retrieve real-time and historical insights from the Bitcoin blockchain using powerful JSON-RPC methods.
One of the primary tools for this is the getchaintxstats RPC, which returns aggregate statistics about transaction volume across a specified block range. You can use it to monitor:
- Average number of transactions per second
- Total number of blocks processed
- Cumulative transaction count over time
- Growth trends in network usage
Additionally, you can define a custom window using either a starting block number or block hash, allowing granular analysis of specific periods—ideal for compliance reporting or market behavior studies.
This capability supports use cases such as:
- Building blockchain explorers
- Powering anti-money laundering (AML) systems
- Generating market intelligence dashboards
- Auditing institutional transaction flows
By integrating these insights into your applications, you gain a deeper understanding of network health and user behavior—all without running your own archival nodes.

Verify Messages Signed with a Bitcoin Key Pair
Security and identity verification are foundational in decentralized systems. Bitcoin wallets generate a cryptographic key pair—consisting of a private key and a corresponding public key—that enables users to sign transactions and prove ownership.
Beyond transactions, users can also digitally sign arbitrary messages using their private key. This feature is commonly used to:
- Authenticate identity in decentralized applications (dApps)
- Prove control over a Bitcoin address during KYC processes
- Secure communications between parties
The process works as follows:
- A user signs a message with their private key.
- The recipient uses the sender’s public key (or Bitcoin address) to verify the signature.
- If valid, it confirms that only someone with access to the private key could have created the signature.
Amazon Managed Blockchain Access Bitcoin supports the verifymessage JSON-RPC method, enabling automated validation of signed messages at scale. This allows platforms to verify user ownership without requiring fund movement—enhancing both security and user experience.
For example, a crypto exchange could use this method during account recovery or withdrawal authorization workflows to confirm address ownership securely.
This functionality strengthens trustless interactions across web3 ecosystems and supports growing demand for self-sovereign identity models.
Monitor the Bitcoin Mempool in Real Time
The mempool (short for memory pool) is where unconfirmed transactions wait before being included in a block. Monitoring this space is essential for many applications that need visibility into pending activity on the Bitcoin network.
Use cases include:
- Tracking confirmation status of outgoing payments
- Detecting double-spend attempts
- Estimating optimal transaction fees
- Identifying high-priority or spam transactions
AMB Access Bitcoin supports several key JSON-RPCs for mempool interaction:
getrawmempool– Retrieve a list of all transaction IDs currently in the mempoolgetmempoolentry– Get detailed information about a specific transaction in the mempoolgetmempoolancestors– View all ancestor transactions of a given mempool entry (useful for fee estimation in chained transactions)testmempoolaccept– Pre-validate a transaction to check if it would be accepted by the node based on current network rules
The testmempoolaccept method is particularly valuable—it allows developers to simulate transaction submission and detect potential issues (e.g., insufficient fees, invalid scripts) before broadcasting. This reduces failed transactions and improves user experience in wallets and trading platforms.
Exchanges, payment processors, and high-frequency traders benefit significantly from real-time mempool access, enabling faster decision-making and better risk management.
