Artisyn is a decentralised protocol built on Stellar that connects local artisans with users through community-curated listings. Our platform creates a trustless ecosystem where skilled workers can be discovered, verified, and compensated securely without relying on centralised intermediaries.
Many artisans lack a platform to help them get noticed; meanwhile, numerous people would appreciate quality artisan recommendations—the kind we aim to provide. Our vision is to be the bridge connecting both worlds.
Telegram ChannelResource usage and estimated fees for the two core market functions, measured
using the Soroban SDK's built-in invocation metering
(env.cost_estimate().resources() / .fee()). Fee rates are based on a
Pubnet snapshot from 2024-12-11 (fee_per_instruction_increment = 25 stroops / 10 000 instructions).
Note on methodology: Contracts run as native Rust inside the test environment, not as compiled WASM. CPU instruction counts are therefore a lower bound — WASM execution adds VM instantiation and bytecode decoding overhead on top. The
persistent_entry_rentfigures are also inflated in the test environment because the TTL extension of 500 000 ledgers is applied to brand-new entries starting from ledger 0; on Mainnet, where entries already carry an existing TTL, the incremental rent cost is far lower. For exact pre-submission estimates, usestellar contract invoke --costagainst a Testnet or Mainnet RPC endpoint.
