Anchor Assets on Stellar

Anchors play a pivotal role in the Stellar ecosystem, acting as bridges between the ledger’s digital realm and the traditional financial world. They serve as both on and off-ramps, enabling the conversion between fiat currencies and their digital counterparts on the Stellar network.

Anchor Functionality:

• Accept Deposits: Anchors take fiat deposits through traditional financial mechanisms and issue corresponding digital tokens on Stellar.
• Facilitate Withdrawals: They allow users to redeem digital tokens for fiat currency, effectively removing the digital representation and releasing the fiat funds back to the user.
• Interoperability Standards: Anchors operate under Stellar Ecosystem Proposals (SEPs), ensuring a consistent and interoperable experience across different services and platforms.
  Anchor Integration:
• Client Applications: Wallets and other client applications interact with anchors via SEPs to facilitate user transactions.
• SEP Server: The SEP server processes client requests, interacts with the Stellar network, and communicates with the anchor’s business server for non-blockchain related operations.
• Anchor Platform Architecture:
• Anchor Platform: It encompasses various components such as the SEP server, a database, and internal servers for managing transactions and observing the Stellar network.
• Business Server: A crucial component that anchors need to implement, it processes business logic and communicates with the SEP server for transaction updates and other operational data.

Building Applications on Stellar

Developing on the Stellar network offers a variety of tools and capabilities for builders. It caters to the creation of financial applications that leverage the speed, low cost, and flexibility of the Stellar ledger.

Development Approach:

Soroban SDKs

For developers interested in building smart contracts on Stellar’s Soroban platform, there are specific SDKs available. These provide specialized tools for writing, deploying, and interacting with smart contracts on the Stellar network.

Soroban is Stellar’s smart contracts platform, which has been designed with a focus on scalability, sensibility, and providing a consistent and high-quality developer experience. It aims to set a new standard for smart contracts by being both developer-friendly and built to scale. Soroban operates on the principle of being a “batteries-included” platform, offering developers the necessary tools to get started quickly and effectively. It includes a local sandbox for development, a set of host functions, and built-in contracts. Soroban is built using Rust, leveraging the Rust ecosystem for safe and efficient tools.

One of the key aspects of Soroban is its scalability, with a design that supports concurrency and efficient transaction processing. It introduces a gas model that closely correlates the computation resources used and the fees, aiming to maximize throughput and reduce costs. Soroban is also addressing the challenge of ledger bloat by designing a state archiving mechanism.

Soroban is not solely dependent on Stellar and can be used by any transaction processor, including other blockchains and permissioned ledgers. However, its integration with the Stellar network allows it to provide reliable access to financial rails, leveraging Stellar’s global anchor network and existing infrastructure for on and off-ramps.

As of the last update, Soroban was live on Testnet, and developers were encouraged to participate in testing and providing feedback. The platform is supported by a $100 million adoption fund from the Stellar Development Foundation, aimed at incentivizing development and adoption.
