General Data
- Project Title: Passive Investment in Liquidity Pools: Historical Analysis of Solana, Raydium Operation, and Optimized Fiscal Strategies in Costa Rica.
- Author: Pedro Gerardo Herrera Abarca.
- Date: December 2025.
- Course/Subject: [E.g., Digital Finance or Blockchain Economics – Adjust according to university context].
- General Objective: Analyze the potential of passive investments in liquidity pools through platforms like Raydium on the Solana blockchain, evaluating its history, fiscal implications in Costa Rica, and a practical example with an initial investment of $100 in a standard pool with 262% APR, integrating a personal case with the k.co.cr platform.
- Specific Objectives:
- Detail the historical evolution of Solana and blockchain networks.
- Examine the tax extensions and total fiscal obligations for cryptoassets at Hacienda in Costa Rica as of 2025.
- Generate a numerical example of a liquidity pool in Raydium with 262% APR, explaining APR vs. APY, starting from a $100 investment.
- Justification: In a context of economic volatility in Costa Rica, passive investments in crypto offer high returns (e.g., 262% APR in Raydium.io pools), but require understanding of their technological and fiscal base to minimize risks. This project proposes a legal "financial ninja" approach, applied to a personal platform like k.co.cr, which includes liquidity sections and a proprietary token for pools.
- Methodology: Qualitative analysis of historical and regulatory sources, combined with quantitative calculations of returns (using APR/APY formulas). Sources include official sites like raydium.io and Hacienda regulations.
Introduction
Blockchain has transformed global finance, enabling passive investments like liquidity pools on decentralized platforms (DEX). Raydium, an Automated Market Maker (AMM) on Solana, stands out for its high yields in pools, such as the standard one with 262% APR. This project explores its feasibility in Costa Rica, where cryptocurrencies are not legal tender but are treated as virtual assets subject to general taxes. Integrating a practical case with k.co.cr (a personal platform that displays liquidity in cash and a token for pools), it seeks to optimize gains while minimizing fiscal burdens, assuming a passive approach to avoid excessive procedures.
Section 1: History of Solana and Blockchain Networks
Blockchain networks emerged with Bitcoin in 2009, introducing a decentralized ledger based on Proof of Work (PoW) for secure transactions without intermediaries. Ethereum (2015) added smart contracts, boosting DeFi and NFTs, but with scalability limitations. Subsequent blockchains like Cardano (PoS) and Polkadot improved efficiency and connectivity.
Solana, founded in 2017 by Anatoly Yakovenko (ex-Qualcomm), solves the blockchain trilemma (scalability, security, decentralization) with Proof of History (PoH), a timestamp system that enables up to 65,000 transactions per second (TPS) at low cost, combined with PoS. The initial whitepaper was published in 2017, and the mainnet launched in March 2020 by Solana Labs, with Raj Gokal as co-founder. Despite outages in 2021-2022, Solana has grown in DeFi and gaming, with its SOL token for staking and fees. Raydium.io, a DEX AMM on Solana, leverages this speed for efficient liquidity pools, where users provide liquidity to token pairs and earn fees/yields, as in standard pools with high APR. This facilitates passive investments, aligned with platforms like k.co.cr.
Section 2: Tax Extensions at Hacienda and Total Obligations
In Costa Rica as of 2025, there is no exclusive tax law for cryptocurrencies; the Bill 23.415 (Cryptoassets Market) remains in debate, adopting a non-interventionist approach. Cryptos are classified as virtual assets, similar to stocks, subject to Hacienda's general rules.
- Income Tax: Capital gains (sale/exchange) are taxed at 15% on net profit (sale minus base cost). If habitual (e.g., trading on Raydium), it falls under progressive income: 0% up to ₡4 million annually, 10-30% on excess. Foreign gains (e.g., pools on international raydium.io) are exempt due to territoriality – key for financial ninjas.
- VAT: Exempt for pure financial activities like staking/pools without commissions; 13% if fees are charged on k.co.cr, unless it qualifies as exempt intermediation.
- Others: No specific wealth tax, but solidarity applies if assets exceed thresholds. For VASPs (e.g., if k.co.cr grows), register with SUGEF for AML/KYC.
Obligations: Annual declaration in D-101 (March-April), record deductions (Raydium fees, k.co.cr hosting) to reduce taxable base. Report transactions >₡6 million for AML; exchanges report to Hacienda starting 2025. Recommendation: Consult a tax advisor to justify minimal surplus.
Section 3: Example of Standard Pool in Raydium with 262% APR, Meaning of APR/APY and Difference
APR (Annual Percentage Rate): Nominal annual simple rate, without compounding – represents the projected base yield in Raydium pools.
APY (Annual Percentage Yield): Effective annual rate with compounding (reinvestment), higher the more frequent (daily/continuous in DeFi).
Difference: APR ignores reinvestment; APY includes it, amplifying gains in volatile pools.
Example: Initial investment of $100 in a standard liquidity pool in Raydium with 262% APR (r = 2.62). Assume foreign source (exempt in CR).
- With simple APR (no compounding): Earnings = $100 * 2.62 = $262. Total: $362.
- With APY and daily compounding (365 days, common in Raydium): APY ≈ 1260.78%. Earnings ≈ $1260.78. Total ≈ $1360.78.
- With continuous compounding (ideal approximation): APY ≈ 1273.57%. Earnings ≈ $1273.57. Total ≈ $1373.57.
Calculations: Daily APY = (1 + r/365)^365 - 1; continuous = e^r - 1. Declare only realized gains (withdrawal to colones), deducting fees to minimize taxes. In k.co.cr, integrate this into the liquidity section for passive monitoring.
Conclusion
This proposal demonstrates that passive investments in Raydium (raydium.io) on Solana offer high potential (up to 1273% APY with $100), optimized fiscally in Costa Rica through foreign exemptions and deductions. Applied to k.co.cr, it promotes a legal and passive ninja approach. Future suggestions: Monte Carlo simulations for volatility risks.
