Why We Built $YFIN
In early 2026, we were pitching Cikal Studio Labs to potential clients as a blockchain and software development agency. The feedback was consistent: "Show us something you've built." We had portfolio pieces, but nothing that demonstrated the full scope of what we could do.
So we decided to build our own ecosystem — not as a side project, but as a serious live product backed by real business revenue from PT Cikal Tuna Mandiri, our yellowfin tuna export company in Eastern Indonesia.
The Architecture Decision
Most token projects launch a token, create a website, and call it an ecosystem. We did the opposite: we designed the full product map first, then built in parallel.
Products Built
- $YFIN Token — BEP-20, 1B fixed supply, 0% tax, non-mintable. Contract: 0xF576bcFac...
- YFinDEX — Custom DEX built on PancakeSwap V2 Router with YFIN fee discounts
- YFINPad — IDO Launchpad with no-code token deployment and vesting
- YFIN Shield — Web3 security toolkit: honeypot checker, rug pull detector, approval revoker
- YFIN Studio — Smart contract-as-a-service: BEP-20, vesting, NFT, RWA contracts
- YFIN Pay — Payment protocol where every transaction burns $YFIN
- YFIN Intelligence — On-chain analytics: whale tracking, token signals, hold-tiered access
- YFIN Monitor — Live token dashboard: price, holders, TX history, vesting countdown
- YFIN Hub — Community platform with KOL showcase and live stats
- yfin.io — Main project site with live RWA data and whitepaper
The RWA Backing Model
This is what makes $YFIN fundamentally different from speculative tokens. PT Cikal Tuna Mandiri sells yellowfin tuna to Japanese buyers — 228.9 tons and $436K in verified transactions across 38 deals.
For every kilogram of verified tuna sold, Rp 50 goes into the buyback & burn program. This creates a direct connection between real commodity exports and token value. The buyback triggers are: InterFi audit complete ✓, LP above $3K ✓, MEXC Global listing (pending).
Key insight: The RWA model solves the fundamental problem of most DeFi tokens — no real value backing. By tying buyback to actual tuna export revenue, $YFIN has a floor that pure speculative tokens don't have.
Technical Challenges We Solved
BSC RPC Quirk
BNB Chain nodes sometimes return to: "" for contract creation transactions, which crashes ethers v6's formatTransactionResponse. Our workaround: detect this case and fall back to eth_getTransactionReceipt via curl before parsing.
Switching from Moralis to Direct RPC
We initially used Moralis for balance and transaction history on monitor.yfin.io. After reliability issues, we switched to direct RPC using eth_call and eth_getLogs. More resilient, zero API cost, full control.
Treasury Vesting on BSCScan
We deployed five separate Treasury Vesting contracts (520M YFIN total) all with cliff November 8, 2026. Getting all five verified on BSCScan and visible in the Wallet Transparency section of monitor.yfin.io took careful coordination but is now a major trust signal — 86.64% of supply is demonstrably locked.
Listing Strategy
We reached 17+ platforms in the first month. The sequence:
- DexScreener — auto-listed, then claimed and verified
- GeckoTerminal — submitted, approved in 48h
- CoinSniper, CoinVote, DEXTools, PooCoin — community platforms, self-submitted
- CoinGecko — pending (requires volume history + active trading)
- CoinMarketCap — pending (stricter requirements)
- MEXC Global — target CEX (after CoinGecko listing)
What We Learned
- Simple contracts pass audits. Using OpenZeppelin base + minimal custom logic = 0 critical findings.
- Transparency compounds trust. Every wallet is public, every vesting contract is verified. Investors notice.
- RWA backing changes the conversation. "What backs this?" is the first question from serious investors — having a real answer is everything.
- 10 products is too many to launch simultaneously. We managed it because it's our own project, but for clients we always recommend phased rollout.
Results
Six months in: token live on BSC, 10 products in production, InterFi audit passed, 17+ platforms listed, $436K in verified RWA revenue, and most importantly — a live portfolio we can show any potential client.
Cikal Studio Labs went from "promising agency" to "here's 10 live products you can use right now." That's the power of eating your own cooking.
