Architect Deterministic Contract Address Derivation for Template DeFi Deployments

[temma02]

Description

Implement deterministic contract address derivation so that template DeFi deployments produce predictable contract addresses, enabling pre-deployment address computation and verification.

Requirements and Context

• Correctness: Derived addresses must match actual deployed addresses
• Testing: Test address derivation against known deployments
• Documentation: Document the derivation algorithm

Suggested Execution

Branch: feat/issue-077-deterministic-contract-address-derivation

Implement Changes

• Implement contract address derivation in packages/stellar/src/soroban.ts
• Derive the address from deployer, salt, and WASM hash per Soroban rules
• Add a pre-deployment address preview to the deployment flow
• Verify the derived address matches the actual address after deployment

Test and Commit

• Test address derivation against known-good fixtures
• Test that derived addresses match post-deployment addresses
• Document the derivation algorithm

Example Commit Message

feat(soroban): add deterministic contract address derivation

- Derive contract address from deployer, salt, and WASM hash
- Add pre-deployment address preview
- Verify derived address matches deployed address

Guidelines

• Follow the official Soroban address derivation specification
• Validate derivation against testnet deployments
• Surface the derived address in the deployment preview
